specializations and those that are done as part of rewrites.
Do not create Subst* nodes in the latter. We previously had a hybrid of
these two behaviors where we would only create some Subst* nodes but not
others during deduction guide rewrites.
No functional change intended, but the resulting ASTs are more
principled.
This patch implements builtins for the following prototypes for the VSX Permute

vector unsigned char vec_genpcvm (vector unsigned char, const int);
vector unsigned short vec_genpcvm (vector unsigned short, const int);
vector unsigned int vec_genpcvm (vector unsigned int, const int);
vector unsigned long long vec_genpcvm (vector unsigned long long, const int);

This is the integer sibling to D81491.
(a[0] + a[1] + a[2] + a[3]) - (b[0] + b[1] + b[2] +b[3]) -->
(a[0] - b[0]) + (a[1] - b[1]) + (a[2] - b[2]) + (a[3] - b[3])
Removing the "experimental" from these intrinsics is likely
not too far away.
Add disassembly support for the movw, adiw, and sbiw instructions.
I had previously committed test cases for the adiw and sbiw
instructions, but had accidentally made them not runnable so they were
skipped all this time. Oops. This patch fixes that by adding support for
disassembling those instructions.

Some instructions have a fixed Z register and don't have an explicit
register operand. This can be worked around by simply printing the
operand directly if the particular register class is detected.
The LPM and ELPM instructions also needed a custom decoder, which is
also included in this patch.

These can often only use a limited range of registers, and apparently
need special decoding support.

This is a set of instructions that take just a single register as an
operand, with no immediates. Because all instructions share the same
format, I haven't added exhaustive bit testing to all instructions but
just to the inc instruction.

I'm not entirely sure why this was ever needed, but when I remove both
adjustments all tests still pass.
This fixes a bug where a long branch (using the `jmp` instead of the
`rjmp` instruction) was incorrectly adjusted by 2 because it jumps to an
absolute address instead of a PC-relative address. I could have added
AVR::fixup_call to the list of exceptions, but it seemed more sensible
to me to just remove this code.

inner non-type pack at a different index.
We previously considered the index of the outer pack (which would refer
to an unrelated template parameter) to be deduced by deducing the inner
pack, because we inspected the (largely meaningless) type of an expanded
non-type template parameter pack.
- Fixed a bug in hasNItems()
- Extend the STLExtras unit test to test hasSingleElement() and hasNItems() and friends.

Summary:
This patch addresses https://bugs.llvm.org/show_bug.cgi?id=46256
The spec of coroutine requires that the expression co_await promise.final_suspend() shall not be potentially-throwing.
To check this, we recursively look at every call (including Call, MemberCall, OperatorCall and Constructor) in all code
generated by the final suspend, and ensure that the callees are declared with noexcept. We also look at any returned data
type that requires explicit destruction, and check their destructors for noexcept.
This patch does not check declarations with dependent types yet, which will be done in future patches.
Updated all tests to add noexcept to the required functions, and added a dedicated test for this patch.
This patch might start to cause existing codebase fail to compile because most people may not have been strict in tagging
all the related functions noexcept.

Add option to filter which op the OpDefinitionsGen run on. This enables having multiple ops together in the same TD file but generating different CC files for them (useful if one wants to use multiclasses or split out 1 dialect into multiple different libraries). There is probably more general query here (e.g., split out all ops that don't have a verify method, or that are commutative) but filtering based on op name (e.g., test.a_op) seemed a reasonable start and didn't require inventing a query specification mechanism here.

Summary: Previous code would try to verify DW_AT_ranges and if any ranges would overlap, it would stop attributing any ranges after this to the DIE which caused incorrect errors to be reported that a DIE's address ranges were not contained in the parent DIE's ranges. Added a fix and a test.

This reverts 057c9c7ee0
This was orignally done so we could separate the compatibility
values and the llvm internal only features into a separate entries
in the feature array. This was needed when we explicitly had to
convert the feature into the proper 32-bit chunk at every reference
and we didn't want things moving around.
Now everything is in an array and we have helper funtions or macros
to convert encoding to index. So we renumbering is no longer an
issue.
Treat function result like dummy argument: a SAVE statement without an
entity-list does not make it saved.

Currently, in order to extract an element from a bf16 vector, we cast
the vector to an i16 vector, perform the extraction, and cast the result to
bfloat. This behavior was copied from the old fp16 implementation.
The goal of this patch is to achieve optimal code generation for lane
copying intrinsics in a subsequent patch (LLVM fails to fold certain
combinations of bitcast, insertelement, extractelement and
shufflevector instructions leading to the generation of suboptimal code).

Prevent fixes being displayed if usages are found in the scratch buffer.
See [[ https://bugs.llvm.org/show_bug.cgi?id=46219 | Fix-It hints are being generated in the ScratchBuffer ]].
It may be wise down the line to put in a general fix in clang-tidy to prevent ScratchBuffer replacements being applied, but for now this will help.

Add a new builtin-function __builtin_expect_with_probability and
intrinsic llvm.expect.with.probability.
The interface is __builtin_expect_with_probability(long expr, long
expected, double probability).
It is mainly the same as __builtin_expect besides one more argument
indicating the probability of expression equal to expected value. The
probability should be a constant floating-point expression and be in
range [0.0, 1.0] inclusive.
It is similar to builtin-expect-with-probability function in GCC
built-in functions.

This requires changing some tests. Most were straightforward, but
codegenprepare-produced-address-math.ll is tricky. One of its RUNs runs
CodeGenPrepare. I tried porting CodeGenPrepare to the NPM, but ended up
getting stuck when I needed a TargetMachine. NPM doesn't have support
for MachineFunctions yet. So I just deleted that RUN line, since it was
mass-added in https://reviews.llvm.org/D54848 and is likely not that
useful.
