[InstCombine] Remove side effect of replaced constrained intrinsics
If a constrained intrinsic call was replaced by some value, it was not
removed in some cases. The dangling instruction resulted in
[InstCombine] Remove side effect of replaced constrained intrinsics
If a constrained intrinsic call was replaced by some value, it was not
removed in some cases. The dangling instruction resulted in useless
instructions executed in runtime. It happened because constrained
intrinsics usually have side effect, it is used to model the interaction
with floating-point environment. In some cases side effect is actually
absent or can be ignored.
This change adds specific treatment of constrained intrinsics so that
their side effect can be removed if it actually absents.

but often the side effect is actually absent or can be ignored.
