This reverts commit e2ad4f17 because it
does not correctly fix the sanitizer buildbot breakage.

Adds a fallback to use the debuginfod client library (386655) in `findDebugBinary`.
Fixed a cast of Erorr::success() to Expected<> in debuginfod library.
Added Debuginfod to Symbolize deps in gn.
Adds new symbolizer symbols to `global_symbols.txt`.

This patch creates sub-directory libcxxabi/test/vendor/ibm and adds 2 LIT test cases for the AIX EH under the directory. One tests the restoration of the condition register and the other tests the restoration of vector registers. Both are saved on the stack by the function prologue.

The problem with the old scheme is that we would need to keep track of
the "next region" and reset the num_threads value after it. The new RT
doesn't do it and an assertion is triggered. The old RT doesn't do it
either, I haven't tested it but I assume a num_threads clause might
impact multiple parallel regions "accidentally". Further, in SPMD mode
num_threads was simply ignored, for some reason beyond me.

In any case, parallel_51 is designed to take the clause value directly,
so let's do that instead.

G_PTR_ADD takes arguments of two different types, so it probably shouldn't be
considered commutative just on that basis. A recent G_PTR_ADD reassociation
optimization (https://reviews.llvm.org/D109528) can emit erroneous code if the
pattern matcher commutes the arguments; this can happen when the base pointer
was created by G_INTTOPTR of a G_CONSTANT and the offset register is variable.

This was discovered on the llvm-mos fork, but I added a failing test case that
should apply to AArch64 (and more generally).

This reapplies a fix from 948ce4e6,
whichn't originally submitted upstream. I has now been merged upstream
though, in https://github.com/google/benchmark/pull/1302.

When benchmarks were unified in
5dda2efd, it lost this change,
but it also lost another local modification, where benchmark's
CMakeLists.txt was modified to comment out adding -Werror.
(This change was part of the original import in
0addd170.)

As the benchmark library is built automatically by default, when
building all of LLVM (contrary to the copy in libcxx, which wasn't
built by default), building it with -Werror by default is very brittle.

This fixes building LLVM with MinGW. (It wasn't broken in MSVC
mode, as the benchmark library doesn't add -Werror or anything
equivalent in MSVC mode, and it's unclear if this warning is
enabled in that mode at all.)

Reapply #2 of [runtimes] Fix building initial libunwind+libcxxabi+libcxx with compiler implied -lunwind

This does mostly the same as D112126, but for the runtimes cmake files.
Most of that is straightforward, but the interdependency between
libcxx and libunwind is tricky:

Libunwind is built at the same time as libcxx, but libunwind is not
installed yet. LIBCXXABI_USE_LLVM_UNWINDER makes libcxx link directly
against the just-built libunwind, but the compiler implicit -lunwind
isn't found. This patch avoids that by adding --unwindlib=none if
supported, if we are going to link explicitly against a newly built
unwinder anyway.

Since the previous attempt, this no longer uses
llvm_enable_language_nolink (and thus doesn't set
CMAKE_TRY_COMPILE_TARGET_TYPE=STATIC_LIBRARY during the compiler
sanity checks). Setting CMAKE_TRY_COMPILE_TARGET_TYPE=STATIC_LIBRARY
during compiler sanity checks makes cmake not learn about some
aspects of the compiler, which can make further find_library or
find_package fail. This caus...
