clang: Add __builtin_elementwise_rint and nearbyint
These are basically the same thing and only differ for strictfp, so add both for future proofing. Note all the elementwise functions are currently broken for strictfp, and use non-constrained ops. Add a test that demonstrates this, but doesn't attempt to fix it.
