As discussed in https://reviews.llvm.org/D73206#1871895> simplifying
usage of `user_id_t`.

There is even written:
  // The compile unit ID is the index of the DWARF unit.
  DWARFUnit *dwarf_cu = info->GetUnitAtIndex(comp_unit->GetID());

Commit 82b47b29 changes the way the stdlib.h
header is structured which seems to cause strange lookup failures in the modules
build. This updates a few failing tests so that they pass with the new
behavior of stdlib.h.

See the discussion in https://reviews.llvm.org/rG82b47b2978405f802a33b00d046e6f18ef6a47be

It can be turned into a sub with -128 instead as long as the
carry flag isn't used.

This wouldn't work for s33-s63 sources.

These aren't using any local state

This patch removes the explicit call graph for CUDA/HIP/OpenMP deferred
diagnostics generated during parsing since it is error prone due to
incomplete information about function declarations during parsing. In stead,
this patch does a post-parsing AST traverse and emits deferred diagnostics
based on the use graph implicitly generated during the traverse.

The driver version of the flag seems to confuse goma.

On Powerpc, set instruction count as lsr first priority of lsr by default.
Add an option ppc-lsr-no-insns-cost to return back to default lsr cost model.

norecurse function attr indicates the function is not called recursively
directly or indirectly.

Add norecurse to OpenCL functions, SYCL functions in device compilation
and CUDA/HIP kernels.

Although there is LLVM pass adding norecurse to functions, it only works
for whole-program compilation. Also FE adding norecurse can make that
pass run faster since functions with norecurse do not need to be checked
again.

[X86] Increase latency of port5 masked compares and kshift/kadd/kunpck instructions in SKX scheduler model

Uops.info shows these as 4 cycle latency.

Add fixits for messaging self in MRR or using super, as the intent is
clear, and it turns out people do that a lot more than expected.

Allow for objc_direct_members on main interfaces, it's extremely useful
for internal only classes, and proves to be quite annoying for adoption.

Add some better warnings around properties direct/non-direct clashes (it
was done for methods but properties were a miss).

Add some errors when direct properties are marked @dynamic.

This allows some simplification.

Both of those functions only have a single caller starting
at LowerSETCC. Just handle floating point directly in LowerSETCC.

This removes the need to pass Chain and IsSignaling all the way
down.

Revision 9658d895 breaks the clang-x64-windows-msvc build bot [1].
This should fix the unit test using the same method as used in 9658d895.

Note I don't have access to a Windows system so the patch is based on the
errors generated by the bot.

Summary:
Many directives are unavailable, and support for others may be limited.

This first draft has preliminary support for:
    - conditional directives (including errors),
    - data allocation (unsigned types up to 8 bytes, and ALIGN),
    - equates/variables (numeric and text),
    - and procedure directives (without parameters),
as well as COMMENT, ECHO, INCLUDE, INCLUDELIB, PUBLIC, and EXTERN. Text variables (aka text macros) are expanded in-place wherever the identifier occurs.

We deliberately ignore all ml.exe processor directives.

Prominent features not yet supported:
    - structs
    - macros (both procedures and functions)
    - procedures (with specified parameters)
    - substitution & expansion operators

Conditional directives are complicated by the fact that "ifdef rax" is a valid way to check if a file is being assembled for a 64-bit x86 processor; we add support for "ifdef <register>" in general, which requires adding a tryParseRegister method to all MCTargetAsmParsers. (Some targets require backtracking in the non-register case.)

Don't copy the IRBuilder when an InsertPointGuard would also do.

Fix a few cases where an IRBuilder is passed to a helper function
by value, while a by reference pass was intended.
