freebsd/tools/build/options/WITH_LLVM_LIBUNWIND
Ed Maste b80f3546a8 Support use of LLVM's libunwind for exception unwinding
It is built in libgcc_s.so and libgcc_eh.a to simplify transition.

It is enabled by default on arm64 (where we previously had no other
unwinder) and may be enabled for testing on other platforms by setting
WITH_LLVM_LIBUNWIND in src.conf(5).

Also add compiler-rt's __gcc_personality_v0 implementation for use with
the LLVM unwinder.
