[X86] Add the FSRM feature (Fast Short Rep Mov) to Zen3.

Note -x86-use-fsrm-for-memcpy is still disabled by default and there's no
default behavior change.

[OpenMP] Dropped unnecessary define when compiling deviceRTLs for NVPTX

The comment said CUDA 9 header files use the `nv_weak` attribute which
`clang` is not yet prepared to handle. It's three years ago and now things have
changed. Based on my test, removing the definition doesn't have any problem on
my machine with CUDA 11.1 installed.

[GWP-ASan] Minor refactor of optional components.

In preparation for the inbuilt options parser, this is a minor refactor
of optional components including:
 - Putting certain optional elements in the right header files,
 according to their function and their dependencies.
 - Cleaning up some old and mostly-dead code.
 - Moving some functions into anonymous namespaces to prevent symbol
 export.
