b280ee1dd7 [test] Use -passes=instsimplify instead of -instsimplify in a number of tests. NFC 
Another step moving away from the deprecated syntax of specifying
pass pipeline in opt.

52900486a1 [FPEnv][InstSimplify] Constrained FP support for NaN 
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".

60a8edf30d [FPEnv][InstSimplify] Precommit tests for 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.
