This is originally based on a patch from David Chisnall for soft-float N64 but has since been updated to support O32, N32, and hard-float ABIs. The soft-float O32, N32, and N64 support has been committed upstream. The hard-float changes are still in review upstream. Enable LLVM_LIBUNWIND on mips when building with a suitable (C+11-capable) toolchain. This has been tested with external GCC for all ABIs and O32 and N64 with clang.
