This is a cherrypick of D64237 onto llvm/utils/benchmark and
libcxx/utils/google-benchmark.

Disabled CMake get_git_version as it is meaningless for this in-tree
build, and hardcoded a null version.
Not using get_git_version avoids a refresh of the git index that is
executed by get_git_version. Refreshing the index can take a
considerable amount of time if the index needs to be refreshed
(particularly with the mono repo). This situation can arise when
building shared source on a host in VMs.

This patch disables exceptions in Microsoft STL when exception
handling is not enabled in Benchmark project. It fixes Windows
builds that were failing due to C4530 warnings thrown by MS STL.

This fixes building for Windows on ARM, with MinGW headers.
(Building for Windows on ARM with Windows SDK still is unsupported
by the benchmark library.)

The windows SDK headers don't have self-consistent casing anyway,
so we consistently use lowercase for these in other places, in order
to fix crosscompilation with mingw headers.
This applies an upstream commit:

`MSVC` is true for clang-cl, but `"${CMAKE_CXX_COMPILER_ID}" STREQUAL
"MSVC"` is false, so we would enable -Wall, which means -Weverything
with clang-cl, and we get tons of undesired warnings.
Use the simpler condition to fix things.

This patch applies upstream commit:

Tim Northover pointed out that benchmark build might be broken on 32-bit
macOS. This commit by Roman Lebedev (lebedev.ri) resolves the issue.

ompiling benchmark library (introduced in D50894) with the latest
bootstrapped Clang produces a lot of warnings, this issue was addressed
in the upstream patch I pushed earlier.

This patch pulls google/benchmark v1.4.1 into the LLVM tree so that any
project could use it for benchmark generation. A dummy benchmark is
added to `llvm/benchmarks/DummyYAML.cpp` to validate the correctness of
the build process.
The current version does not utilize LLVM LNT and LLVM CMake
infrastructure, but that might be sufficient for most users. Two
introduced CMake variables:
* `LLVM_INCLUDE_BENCHMARKS` (`ON` by default) generates benchmark
targets
* `LLVM_BUILD_BENCHMARKS` (`OFF` by default) adds generated
benchmark targets to the list of default LLVM targets (i.e. if `ON`
benchmarks will be built upon standard build invocation, e.g. `ninja` or
`make` with no specific targets)
List of modifications:
* `BENCHMARK_ENABLE_TESTING` is disabled
* `BENCHMARK_ENABLE_EXCEPTIONS` is disabled
* `BENCHMARK_ENABLE_INSTALL` is disabled
* `BENCHMARK_ENABLE_GTEST_TESTS` is disabled
* `BENCHMARK_DOWNLOAD_DEPENDENCIES` is disabled
