Luís Marques 2f34a6844a [RISCV][PowerPC] Fix google/benchmark benchmark::cycleclock::Now
Cherrypick the upstream fix commit a77d5f7 onto llvm/utils/benchmark
and libcxx/utils/google-benchmark.
This fixes LLVM's 32-bit RISC-V compilation, and the issues
mentioned in https://github.com/google/benchmark/pull/955
An additional cherrypick of ecc1685 fixes some minor formatting
issues introduced by the preceding commit.

LLVM notes
----------
This directory contains the Google Benchmark source code. Currently, the checked
Benchmark library version is v1.4.1.
This directory is under a different license than LLVM.
Changes:
* Bazel BUILD files are removed from the library
* https://github.com/google/benchmark/commit/f85304e4e3a0e4e1bf15b91720df4a19e90b589f
is applied on top of the v1.4.1 to silence compiler warnings
* https://github.com/google/benchmark/commit/505be96ab23056580a3a2315abba048f4428b04e
is applied to comply with the LLVM's required CMake version
* https://github.com/google/benchmark/commit/f0901417c89d123474e6b91365029cfe32cf89dc
is applied to fix 32-bit build failure on macOS
* https://github.com/google/benchmark/commit/52613079824ac58d06c070aa9fbbb186a5859e2c
is applied to fix cross compilation with MinGW headers
* https://github.com/google/benchmark/commit/439d6b1c2a6da5cb6adc4c4dfc555af235722396
is applied to fix building with MinGW headers for ARM
* https://github.com/google/benchmark/commit/a9b31c51b1ee7ec7b31438c647123c2cbac5d956
is applied to disable exceptions in Microsoft STL when exceptions are disabled
* Disabled CMake get_git_version as it is meaningless for this in-tree build,
and hardcoded a null version
* https://github.com/google/benchmark/commit/4abdfbb802d1b514703223f5f852ce4a507d32d2
is applied on top of v1.4.1 to add RISC-V timer support.
* https://github.com/google/benchmark/commit/8e48105d465c586068dd8e248fe75a8971c6ba3a
is applied on top of v1.4.1 to fix cross-build from linux to windows via MinGW.
* https://github.com/google/benchmark/commit/a77d5f70efaebe2b7e8c10134526a23a7ce7ef35
and
https://github.com/google/benchmark/commit/ecc1685340f58f7fe6b707036bc0bb1fccabb0c1
are applied on top of the previous cherrypick to fix timestamp-related inline
asm issues and 32-bit RISC-V build failures. The second cherrypicked commit
fixes formatting issues introduced by the preceding change.
