c0317ac800 Rebase refactored TableGen backends onto LLVM 18.
The MCInstDesc table changed. Bsides this only minor changes were done
and some additional code is emitted now for LLVM.

This commit is the combination of all previous Auto-Sync commits.
The list of commit messages follows:

-----------

Combination of all commits of the refactored tablegen backends.

These are the changes made for LLVM 16.

Refactor Capstone relevant TableGen Emitter backends.

This commit extracts the code which emits generated tables into two printer classes.
The Printer is called whenever actual code is written to a file.
There is the PrinterLLVM which emits tht code as before and
PrinterCapstone which is tailored to or needs (emitting C and generates
more info).

Additionally missing memory access properties were added to ARMs td
files.

Emit a single header for all files.

Captialize Target name for enums.

Add lay metric to emit enum value for Banked and system regs.

Malloc substr

Sort instructions in ascending order.

Free substr after use

Add vanished constrainsts

Fix `regInfoEmitEnums()` and indent

Fix `GenDisassemblerTables.inc#checkDecoderPredicate()`

Fix `TriCoreGenRegisterInfo.inc` | `PrinterCapstone::regInfoEmitRegClasses`

revert changes to NEON instructions

Add instructions with duplicate operands as Matchables.

Add memory load and store info

Correct memory access and out operand info

Set register lists again as read ops due to https://github.com/llvm/llvm-project/issues/62455

Make printAliasInstr and getMnemonic static.

Generate CS instruction enums from actual mnemonic. Not via the flawed AsmMatcher.

Fix typo in InstrInfoEmitter.cpp

Add deprecated QPX feature

Replace + and - with p and m

Add AssemblerPredicates to PPC

Generate RegEncodingTable

Define functions which are called by the Mapper as static.

Necessary because these functions are present in each arch'

Remove set_mem_access().

The cases where this is used to mark access to actual memory operands are
either very rare, or those are neon lane indicies.

Generate correct op type for absolute addresses.

Check for RegisterPointer operands first to prevent mis-categorization.

Add missing Operand types

Generate Instruction formats for PPC.

Add Paired Single instructions.

Partly revert 94e41ce23a7fd863a96288ec05b6c7202c3cfbf1 (introduces accidentially removed code.)

Set correct operand types for PS operands

Add memory read/write attributes

Add missing operand types

Add mayLoad and mayStore information.

Add documentation.

Handle special AArch64 operand

Replace C++ with C code.

Check for duplicate enum instr. names

Check for duplicate defintions of system registers.

Add note about missing target names.

Resolve templates in a single static method and add docs about it.

Revert printing target name in upper case.

Revert partially C++ syntax fixes in .td files.

They break the TemplateCOllector since it searches for exactly those references but can't find any'

Add all SubtargetFeatures to feature enum.

Not just the one used by CGIs.

Pass Decoder

Enable to check specific table fields to determine if reg enum must be emitted.

Allow to add namespace to type name/

Formatting

Rework emitting of tables.

The system operands are now emitted in reg, imm and aliass groups.
Also a bug was fixed which emitted incorrect code..

Check for rename IMPLICIT_IMM operand types

Print undef when it needs to be printed.

Add namespace ids to all types and functions.

Rework C translation.

Pass MCOp as pointer not as ref

Handle edge case for printSVERegOp

Handle default arguments of template functions.

Add two missing op groups

Generate a static RecEncodingTable

Set enum values to encodings of the sys ops

Generate a single Enum value file for system operands.

Replace System operand groups with their operand types

Fix missing braces warning

Emit MCOperand validator.

Emit lookupByName functions for sys operands

Add namespaces for ARM.

Check for Target if default arguments of template functions are resolved.

auto-sync opcode & operand encoding info generation (#14)

* Added operand and opcode info generation

* Wrapped deprecated macro under an intellisense check

Basically intellisense fails, causing multiple errors in other files,

so when intellisense parses the code it will use the different version of the macro

* Fixed a small bug

Used double braces to prevent an old bug

Removed extra new line and fixed a bug regarding move semantics

7fd9979eb9 [InstCombine] Drop UB-implying attrs/metadata after speculating an instruction (#85542)
When speculating an instruction in `InstCombinerImpl::FoldOpIntoSelect`,
the call may result in undefined behavior. This patch drops all
UB-implying attrs/metadata to fix this.

Fixes #85536.

207ecd684c [Arm64EC] Copy import descriptors to the EC Map (#84834)
As noted in <https://github.com/llvm/llvm-project/pull/78537>, MSVC
places import descriptors in both the EC and regular map - that PR moved
the descriptors to ONLY the regular map, however this causes linking
errors when linking as Arm64EC:

```
bcryptprimitives.lib(bcryptprimitives.dll) : error LNK2001: unresolved external symbol __IMPORT_DESCRIPTOR_bcryptprimitives (EC Symbol)
```

This change copies import descriptors from the regular map to the EC
map, which fixes this linking error.

0c1dcd6752 [clangd] [HeuristicResolver] Protect against infinite recursion on DependentNameTypes (#83542)
When resolving names inside templates that implement recursive
compile-time functions (e.g. waldo<N>::type is defined in terms
of waldo<N-1>::type), HeuristicResolver could get into an infinite
recursion, specifically one where resolveDependentNameType() can
be called recursively with the same DependentNameType*.

To guard against this, HeuristicResolver tracks, for each external
call into a HeuristicResolver function, the set of DependentNameTypes
that it has seen, and bails if it sees the same DependentNameType again.

To implement this, a helper class HeuristicResolverImpl is introduced
to store state that persists for the duration of an external call into
HeuristicResolver (but does not persist between such calls).

Fixes https://github.com/clangd/clangd/issues/1951

a649e0a6e8 [clang][modules] giving the __stddef_ headers their own modules can cause redeclaration errors with -fbuiltin-headers-in-system-modules (#84127)
On Apple platforms, some of the stddef.h types are also declared in
system headers. In particular NULL has a conflicting declaration in
<sys/_types/_null.h>. When that's in a different module from
<__stddef_null.h>, redeclaration errors can occur.

Make the \_\_stddef_ headers be non-modular in
-fbuiltin-headers-in-system-modules and restore them back to not
respecting their header guards. Still define the header guards though.
__stddef_max_align_t.h was in _Builtin_stddef_max_align_t prior to the
addition of _Builtin_stddef, and it needs to stay in a module because
struct's can't be type merged. __stddef_wint_t.h didn't used to have a
module, but leave it in it current module since it doesn't really belong
to stddef.h.

bb83f05509 [runtimes] Prefer -fvisibility-global-new-delete=force-hidden (#84917)
27ce26b066 added the new option
-fvisibility-global-new-delete=, where -fvisibility-global-new-delete=force-hidden
is equivalent to the old option -fvisibility-global-new-delete-hidden.
At the same time, the old option was deprecated.

Test for and use the new option form first; if unsupported, try
using the old form.

This avoids warnings in the MinGW builds, if built with Clang 18 or
newer.

122ba9f100 [ELF] Eliminate symbols demoted due to /DISCARD/ discarded sections (#85167)
#69295 demoted Defined symbols relative to discarded sections.
If such a symbol is unreferenced, the desired behavior is to
eliminate it from .symtab just like --gc-sections discarded
definitions.
Linux kernel's CONFIG_DEBUG_FORCE_WEAK_PER_CPU=y configuration expects
that the unreferenced `unused` is not emitted to .symtab
(https://github.com/ClangBuiltLinux/linux/issues/2006).

For relocations referencing demoted symbols, the symbol index restores
to 0 like older lld (`R_X86_64_64 0` in `discard-section.s`).

Fix #85048

8c6015db59 [X86][Inline] Skip inline asm in inlining target feature check (#83820)
When inlining across functions with different target features, we
perform roughly two checks:
 1. The caller features must be a superset of the callee features.
2. Calls in the callee cannot use types where the target features would
change the call ABI (e.g. by changing whether something is passed in a
zmm or two ymm registers). The latter check is very crude right now.

The latter check currently also catches inline asm "calls". I believe
that inline asm should be excluded from this check, as it is independent
from the usual call ABI, and instead governed by the inline asm
constraint string.

Fixes https://github.com/llvm/llvm-project/issues/67054.

c7eb919d2c [ValueTracking] Treat phi as underlying obj when not decomposing further (#84339)
At the moment, getUnderlyingObjects simply continues for phis that do
not refer to the same underlying object in loops, without adding them to
the list of underlying objects, effectively ignoring those phis.

Instead of ignoring those phis, add them to the list of underlying
objects. This fixes a miscompile where LoopAccessAnalysis fails to
identify a memory dependence, because no underlying objects can be found
for a set of memory accesses.

7b61ddefc2 [ArgPromotion] Remove incorrect TranspBlocks set for loads. (#84835)
The TranspBlocks set was used to cache aliasing decision for all
processed loads in the parent loop. This is incorrect, because each load
can access a different location, which means one load not being modified
in a block doesn't translate to another load not being modified in the
same block.

All loads access the same underlying object, so we could perhaps use a
location without size for all loads and retain the cache, but that would
mean we loose precision.

For now, just drop the cache.
