This builds on https://reviews.llvm.org/D49865 to get #pragma STDC FENV_ACCESS ON to and used by AST handling of function calls to math intrinsics. This now emits constrained math intrinsics instead of the regular variety for the ones currently implemented in llvm.

This should be good for C. More work is needed for C++.
