A set of function attributes is required in any function that uses constrained
floating point intrinsics. None of our tests use these attributes.
This patch fixes this.
These tests have been tested against the IR verifier changes in D68233.

This implements constrained floating point intrinsics for FP to signed and
unsigned integers.
Quoting from 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.
