libc++abi: add a top level option for using CompilerRT
Add an option to opt into compiler-rt instead of libgcc. This option defaults
to OFF to avoid a behaviour change. It is not possible to mix and match
different runtime libraries. Disabling this requires that libc++ is built
accordingly. This knob is particularly useful for targets that are GCC by
default (i.e. Linux).
