  MFC: Support for running 32-bit multithreaded binaries using libthr on
  amd64 including:
  - Add 32-bit wrappers for thr_new(), thr_suspend(), and the umtx system
  - Add support to amd64 for constructing thread upcalls for 32-bit
  - Leave %fs and %gs alone in the signal trampoline for 32-bit processes on
  - Add 'casuword32()' to amd64 and ia64.
