Introduce new versions that follow the IEEE semantics
to help with legalization that may need quieted inputs.
There are some regressions from inserting unnecessary
canonicalizes when these are matched from fast math
fcmp + select which should be fixed in a future commit.

The intention is to enable the extract_vector_elt load combine,
and doing this for other operations interferes with more
useful optimizations on vectors.
Handle any type of load since in principle we should do the
same combine for the various load intrinsics.

Handle fmul, fsub and preserve flags.
Also really test minnum/maxnum reductions.
The existing tests were only checking from
minnum/maxnum matched from a fast math compare
and select which is not the same.

This usually results in better code. Fixes using
inline asm with short2, and also fixes having a different
ABI for function parameters between VI and gfx9.
Partially cleans up the mess used for lowering of the d16
operations. Making v4f16 legal will help clean this up more,
but this requires additional work.
