Constrained floating point intrinsics for FP to signed and unsigned integers are still needed.

Quoting from D32319 <https://reviews.llvm.org/D32319>: "The purpose of the constrained intrinsics is to force the optimizer to respect the restrictions that will be necessary to support things like the STDC FENV_ACCESS ON pragma without interfering with optimizations when these restrictions are not needed."

This diff replaces D43515 <https://reviews.llvm.org/D43515>. That ticket has too much history to be easily read.
