Slightly reorganize libclang_rt Makefile again

Make a separate .elif section for MACHINE_ARCH==powerpc, and subdivide
the MACHINE_CPUARCH values under it. If at some point more sanitizer
libraries become available for powerpc CPU architectures, they can be
added before the "nothing for other powerpc yet" case. Similar for the
MACHINE_ARCH==arm case.

Fix building of several libclang_rt libraries for powerpc64 and powerp64le

I reorganized the libclang_rt Makefile in e77a1bb27574 to make it more
readable and maintainable, but the check for 32-bit powerpc was wrong.
This caused almost no libclang_rt libraries to be built for powerpc64
and powerpc64le.

Reorganize libclang_rt Makefile and make more lib/arch combos available

Upstream has made more clang runtime libraries available for more
architectures, so add them. To make this easier, split up subdir lists
into functional parts (asan, tsan, etc), and put each architecture into
its own .if block.

Effectively, this adds the following libraries for aarch64: asan, cfi,
fuzzer, msan, safestack, stats, tsan, ubsan, xray.

powerpc: enable supported sanitizers on powerpc64*

1. Merge LLVM's 315d792130258a9b7250494be8d002ebb427b08f, adding support
for FreeBSD/powerpc64*.
2. Add sanitizer list to lib/libclang_rt/Makefile, taken from the list of
libraries that llvm-devel port builds.
3. powerpc64le supports the same sanitizers that powerpc64, but powerpc64le
also supports xray* sanitizers.
4. lib/libclang_rt/xray/Makefile hardcodes amd64-specific files, so that needs
to be conditionalized.
5. Sanitizers are not enabled for powerpc, because powerpc supports only
builtins and profile.

Rearrange libclang_rt Makefile again, and attempt to simplify it.

It turns out that parts of the common sanitizer code still do not

Build libclang_rt/profile on all clang-supported architectures

There's no reason why a special case needs to be added specifically for amd64,
arm, and i386, as the code is written in machine architecture agnostic C/C++.

This will make it possible for all supporting clang architectures to produce
runtime coverage with `--coverage`.
