Summary:
The callback will be invoked in clangd when we receive a reply from the client.
This is a prerequisite of implementing a generic mechanism for chainable
refactorings (e.g. extract variable and rename), this would allow server to
trigger a new request to the LSP client after receiving a reply from the client.

Currently Target::m_next_persistent_variable_index is counting up
for our persistent variables ($0, $1, ...) but we also have a
unused counter that is supposed to do this in
ClangPersistentVariables but that stays always at 0 (because
we currently increase the target counter when we should increase
that unused counter).
This patch removes the counter in Target and lets the documented
counter in ClangPersistentVariables do the variable counting.
Patch *should* be NFC, but it might unexpectedly bring LLDB to
new code paths that could contain exciting new bugs to fix.

It seems because of the recent refactorings this variable has become unused
and now we get this warning in the build logs:
In file included from llvm/clang/lib/CrossTU/CrossTranslationUnit.cpp:12:
llvm/clang/include/clang/CrossTU/CrossTranslationUnit.h:200:21: warning: private field 'CI' is not used [-Wunused-private-field]

^
I'll remove them for now to get the builds back to green.

Summary: RecursiveASTVisitor was visiting implcit constructor initializers. This caused semantic highlighting in clangd to emit error logs. Fixes this by checking if the constructor is written or if the visitor should visit implicit decls.

With GNU tools, delayload is handled completely differently. (One
creates a specific delayload import library using dlltool and then
links against it instead of the normal import library.)
Instead of requiring using -Xlink=-delayload:lib.dll, we can provide
an lld specific option for this.

These symbols actually point to the symbol's IAT entry, which
obviously is different from the symbol itself (which is imported
from a different module and doesn't exist in the current one).
Omitting this symbol helps gdb inspect automatically imported
symbols, see https://sourceware.org/bugzilla/show_bug.cgi?id=24574
for discussion on the matter.
Surprisingly, those extra symbols don't seem to be an issue for
gdb when the sources have been built with clang, only with gcc.
The actual logic in gdb that this depends on still is unknown, but
omitting these symbols from the symbol table is the right thing to
do in any case.

The commit changed Module dumping code to call SymbolFile::Dump
directly, which meant that we were no longer showing the plugin name in
the output (as that was done in the SymbolVendor).
This adds the plugin name printing code to the SymbolFile dump method,
and tweak the assertions in the PDB tests to match it correctly.

The test case is based on the example from the post-commit thread for:
https://reviews.llvm.org/rGc9171bd0a955
This replaces the x86-specific simple-type check from:
rL367766
with a check in the DAGCombiner. Adding the check isn't
strictly necessary after the fix from:
rL367768
...but it seems likely that we're heading for trouble if
we are creating weird types in this transform.
I combined the earlier legality check into the initial
clause to simplify the code.
So we should only try the trunc/sext transform at the
earliest combine stage, but we limit the transform to
simple types anyway because the TLI hook is probably
too lax about what it considers a free truncate.

This method is dead. It was introduced in D47989,
but now the logic from D63475 is used in llvm-readobj instead.
Also it has a problem: it returns the first matching section,
even if there are multiple sections with the same name.

I have failures in this test because the grep @b gets confused by the
clang version including a repository name like this
!1 = !{!"clang version 10.0.0 (git@build-machine:llvm/llvm-monorepo.git fe958c0e8c89ec663c8e551936778e2cbb460154)"}
I considered something like grep -w but my understanding of the manpages
was that that isn't super portable. So I think it is easier to make
clang not to output that metadata using -fno-ident.

Summary:
The contents of the gnu_debuglink section were passed through the
GetDebugSymbolFilePaths interface, which was more generic than needed.
As the only class implementing this function is ObjectFileELF, we can
modify the function to return just a single FileSpec (instead of a
list). Also, since the SymbolVendorELF already assumes ELF object files,
we don't have to make this method available on the generic ObjectFile
interface -- instead we can put it on ObjectFileELF directly.
This change also makes is so that if the Module has an explicit symbol
file spec set, we disregard the value the value of the debug link
(instead of doing a secondary lookup using that). I think it makes sense
to honor the users wishes if he had explicitly set the symbol file spec,
and this seems to be consistent with what SymbolVendorMacOSX is doing
(SymbolVendorMacOSX.cpp:125).
The main reason for making these changes is to make the treatment of
build-ids and debug links simpler in the follow-up patch.

Summary:
This patch removes the GetSymtab method from the SymbolVendor, which is
a no-op as it's implementation just forwards to the relevant SymbolFile.
Instead it creates a Module::GetSymtab, which calls the SymbolFile
method directly.
All callers have been updated to use the Module method directly instead
of a two phase GetSymbolVendor->GetSymtab search, which leads to reduced
intentation in a lot of deeply nested code.

Add an explicit construction of the ArrayRef, gcc 5 and earlier don't
seem to select the ArrayRef constructor which takes a C array when the
construction is implicit.
Original commit message:
- Avoid a crash when IPRA calls ARMFrameLowering::determineCalleeSaves
with a null RegScavenger. Simply not updating the register scavenger
is fine because IPRA only cares about the SavedRegs vector, the acutal
code of the function has already been generated at this point.
- Add a new hook to TargetRegisterInfo to get the set of registers which
can be clobbered inside a call, even if the compiler can see both
sides, by linker-generated code.

Summary:
This contains various fixes:
- Explicitly determine and return the next noreturn instruction.
- If an invoke calls a noreturn function which is not nounwind we
keep the unwind destination live. This also means we require an
invoke. Though we can still add the unreachable to the normal
destination block.
- Check if the return instructions are dead after we look for calls
to avoid triggering an optimistic fixpoint in the presence of
assumed liveness information.
- Make the interface work with "const" pointers.
- Some simplifications
While additional tests are included, full coverage is achieved only with
D59978.
