This revision is now accepted and ready to land.
Going to accept this pending the backend patch, but when that one is applied I
wanted you to feel OK to add this. A couple of inline nitpick comments and some
agreement that we should do something uniform for fast-math is all.

Would be nice to get these pulled into a single fast-math string that's set and
then used all over for sure. :)

I commented on naming here in the backend patch, but just want to make them the
same.

Shouldn't need to disable the llvm optimizations here.
