As noted in the code comment, a potential follow-on would be to remove the builtins themselves. Other than ord/unord, this already works as expected. Eg:
  typedef float v4sf __attribute__((__vector_size__(16)));
  v4sf fcmpgt(v4sf a, v4sf b) { return a > b; }

I'll link a patch for the corresponding LLVM codegen tests next. A follow-on for that side would be to auto-upgrade and remove the LLVM intrinsics.
