Merge commit 4bb2416d42eb from llvm-project (by Jessica Clarke):

[builtins][AArch64] Implement _sync out-of-line atomics

Whilst Clang does not use these, recent GCC does, and so on systems such
as FreeBSD that wish to use compiler-rt as the system runtime library
but also wish to support building programs with GCC these interfaces are
needed.

This is a light adaptation of the code committed to GCC by Sebastian Pop
<spop@amazon.com>, relicensed with permission for use in compiler-rt.

compilert-rt: build out-of-line LSE atomics helpers for aarch64

Both clang >= 12 and gcc >= 10.1 now default to -moutline-atomics for
aarch64. This requires a bunch of helper functions in libcompiler_rt.a,
to avoid link errors like "undefined symbol: __aarch64_ldadd8_acq_rel".

(Note: of course you can use -mno-outline-atomics as a workaround too,
but this would negate the potential performance benefit of the faster
LSE instructions.)

Bump __FreeBSD_version so ports maintainers can easily detect this.

libcompiler_rt: stop building with stack smashing protection

libcompiler_rt implements certain functions that clang and gcc emit
calls to as part of their codegen (e.g. for extended width math). Build
it without stack smashing protection (SSP, -fstack-protector) in order
to support building binaries without SSP, especially the dynamic linker.
Besides, SSP is probably not very valuable in this library.

Fix llvm-libunwind userspace build on ARM

GCC's libgcc exports a few ARM-specific symbols for ARM EABI, AEABI, or
EHABI or whatever it's called. Export the same ones from LLVM-libunwind's
libgcc_s, on ARM. As part of this, convert libgcc_s from a direct
Version.map to one constructed from component Symbol.map files. This allows
the ARM-specific Symbol.map to be included only on ARM.

Fix ARM-only oddities in struct name/aliases in LLVM-libunwind to match
non-ARM definitions and ARM-specific expectations in libcxxrt /
libcompiler_rt.

No functional change intended for non-ARM architectures.

This commit does not actually flip the switch for ARM defaults from libgcc
to llvm-libunwind, but makes it possible (to compile, anyway).
