Avoids repeating all the extension/legalization wrapper in every use

This isn't expected to reduce compilation times as 'max-iters' is set to
one by default, but it helps with recursive functions that require higher
iteration counts.

[X86] lowerV8I16Shuffle - use explicit SmallVector<SDValue, 4> width to avoid MSVC AVX alignment bug

As discussed on Issue #54645 - building llc with /AVX can result in incorrectly aligned structs

This patch modifies IntegerPolyhedron, IntegerRelation, PresburgerRelation,
PresburgerSet, PWMAFunction, constructors to take PresburgerSpace instead of
dimensions. This allows information present in PresburgerSpace to be carried
better and allows for a general interface.

At present, we are generating wrong code for C++20 modules entities which
should have internal linkage.  This is because we are assigning
'ModuleInternalLinkage' unconditionally to such entities.  However this mode
is only applicable to the modules-ts.

This change makes the special linkage mode conditional on fmodules-ts and
adds a unit test to verify that we generate the correct linkage.

Currently, static variables and functions in module purview are emitted into
object files as external. On some platforms, lambdas are emitted as global
weak defintions (on Windows this causes a mangler crash).

The pointer.volatile.pass.cpp test was already marked as XFAIL for
mingw-dll (for reasons explained in the comment above it).

The same issue also appears in clang-cl-dll when built with newer
CMake versions. (It didn't appear with older versions of CMake, as
CMake built the library with the clang-cl flag `-std:c++latest` when
we've requested C++ 20 - which practically built it in c++2b mode with
current clang versions. With current versions of CMake, it passes
`-std:c++20` instead.)

As it succeeds/fails dependent on factors we don't
directly control, mark it as UNSUPPORTED instead of XFAIL.

Many callers of SendPacket() in RNBRemote.cpp have a local std::string
object, call c_str() on it to pass a c-string, which is then copied into
a std::string temporary object.

Also free JSONGenerator objects once we've formatted them into
ostringstream and don't need the objects any longer, to reduce max
memory use in debugserver.

This solves the multiple defintiion issue

I think the cause of the bug might be an oversight. We just forget to
edit this when implementing partitions. And it should be a good fix.

This shows that pushing constant to the right in a commutative op leads
to `applyPatternsAndFoldGreedily` to converge without applying all the
patterns.

Differential Revision: https://reviews.llvm.org/D122870

Revert "[GreedPatternRewriter] Preprocess constants while building worklist when not processing top down"

This reverts commit 59bbc7a0.

This exposes an issue breaking the contract of
`applyPatternsAndFoldGreedily` where we "converge" without applying
remaining patterns.

This approach is used by AArch64/RISCV to make frame-setup/frame-destroy
instructions contiguous instead of being interleaved by CFI instructions. Code
checking `MBBI->getFlag(MachineInstr::FrameSetup) || MBBI->isCFIInstruction()`
can be simplified to just check FrameSetup.

This helps locate all CFI instructions in the prologue, which can be handy to use
.cfi_remember_state/.cfi_restore_state to decrease unwind table size (D114545).

[llvm-profgen] Fixing a context attribure update issue due to a non-derministic processing order on different platforms.

 A context can  be created by invoking the `getFunctionProfileForContext` function in two ways:
      - by using a probe and its calling context.
      - by removing the leaf frame from an existing contexts. The first way is used when generating a function profile for a given LBR range, and the input `WasLeafInlined` is computed depending on the actually probe in the LBR range. The second way is used when using the entry count of an inlinee function profile to update its inliner callsite count, so `WasLeafInlined` is unknown for the inliner frame.

The two  invocations can happen in different order on different platforms, since the lbr ranges are stored in an unordered_map, and  we are making sure `ContextWasInlined` is always set correctly.

This should fix the random test failure introduced by D121655
