  [HLSL][Matrix] Add implicit matrix floating-point conversion checks (#179568)

Fixes #168944 
Depends on #178762 being merged first.

The commit adds implicit conversion warnings for HLSL matrix types in
Clang's semantic checker by extending SemaChecking.cpp to detect
precision loss when converting between matrix types (specifically,
ConstantMatrixType).
A new test validates float precision warnings, and an existing test was
updated to expect the new diagnostics.

  [VPlan] Use pragma pack(1) for VPIRFlags on AIX. (#184687)

Some compilers (e.g. on AIX) do not pack by default. Use LLVM_PACKED to
ensure the VPIRFlags struct is packed as expected on all platforms.

This matches what we already do in other places for AIX, e.g. in
llvm/include/llvm/CodeGen/SelectionDAGNodes.h (added in
844a02e509a4cc03f76ef5dd1c358c57ee164b71), although it uses the more
general LLVM_PACKED unconditionally

  [clang][modules] Add warning for module maps with ".." paths (#184279)

Implicitly discovered module maps that reference files outside their
module directory cause order dependent behavior when using implicitly
discovered module maps. This adds an off by default diagnostic about
these cases with the long term goal of removing import order dependent
behavior.

Module maps found via `-fmodule-map-file=` are not a problem because
they are all loaded at the start of translation.

  Revert "When hijacking events, don't let the user thread that was allowed"

This reverts commit a8af467fad7e5fff71643a3d6f2d06ac4f637e66.

This was a follow-on to 97572c1860efeeb97b5940927cee72081b61810a which was me
trying to guess why the ubuntu bots were failing with an entirely unhelpful
failure mode.  I'll have to figure out how I can reproduce this somewhere so
I can look at it for real.

This reverts commit 894408ded44151e4e34a3402210f671355d66310.

These tests were added by 97572c1860efeeb97b5940927cee72081b61810a
and I am reverting that as well.

  Revert "Add the ability to "allow another thread to see the private state" mode. (#184272)"

This reverts commit 97572c1860efeeb97b5940927cee72081b61810a.

This patch seems to cause TestWatchpointCommandPython.py to time out
on the ubuntu buildbots (but nowhere else that I can find so far.)  The
timeout is weird too, the TEST FILE is timing out but the individual
tests aren't being shown and there's no other output.  Grrr...
Anyway I'll revert this and then see if I can do some guessing about
how this change might cause the test to fail.
