Kevin P. Neal 727a891ec8 [FPEnv][InstSimplify] Fold fadd X, 0 ==> X, when we know X is not -0 
Currently the fadd optimizations in InstSimplify don't know how to do this
NoSignedZeros "X + 0.0 ==> X" fold when using the constrained intrinsics.
This adds the support.

This review is derived from D106362 with some improvements from D107285
and is a follow-on to D111085.
