In addition, while my employment meant I couldn't add this to libgcc in the past there's no reason why it couldn't be added as well. Has anyone tried?

+1 to trying to add these to libgcc instead of removing from compiler-rt. Both ChromeOS and FreeBSD use llvm-libgcc to make compiler-rt appear as if it is libgcc (but it's still compiler-rt), and this may have unintended consequences. I suspect that there are more systems that do this too.
