The errant test in the previous iteration has been corrected now.
Correct InstSimplify strictfp tests to follow the rules documented
in the LangRef:
https://llvm.org/docs/LangRef.html#constrained-floating-point-intrinsics
Some of these tests needed the strictfp attribute on function
definitions. After D154991 the constrained intrinsics have the
strictfp attribute by default so they don't need it here, but other
functions do.
Test changes verified with D146845.

Currently InstructionSimplify.cpp knows how to simplify floating point
instructions that have a NaN operand. It does not know how to handle the
matching constrained FP intrinsic.
This patch teaches it how to simplify so long as the exception handling
is not "fpexcept.strict".
Differential Revision: https://reviews.llvm.org/D103169
In D103169 I'm adding to InstSimplify support for NaN to constrained
intrinsics that have a regular FP IR instruction counterpart. Precommit
the tests for clarity when that ticket lands.
