Build the unwinder as a separate library.
Since gcc_personality_v0.c from compiler-rt depends on having an
unwinder, but we don't want to pull in _all_ of libc++abi, build the
unwinder as a separate library, libllvmunwind.
This is going to be a part of a larger cleanup where we stop bundling
everything into libc++ and instead link libc++, libc++abi, the
compiler runtime library, and whatever unwinder as separate libraries.
This change probably won't happen until we can select all of these
libraries as the default.
