[InstCombine] Check FPMathOperator for Ctx before FMF check
We need to check FPMathOperator for Ctx instruction before checking fast
math flag on this Ctx.
Ctx is not always an FPMathOperator, so explicitly check for it.
Fixes #71548.

[InstCombine] Regenerate all test checks (NFC)
Due to an improvement to name preservation, a lot of InstCombine
tests now show spurious diffs when regenerated.
Rather than regenerating individual files when they get touched,
mass-regenerate all UTC-based InstCombine tests. I have then reset
a number of files showing suspicious diffs where the UTC output
has clearly been manually adjusted. I apologize if I missed
anything in the mass of changes.

[InstCombine] convert FP min/max with negated op to fabs
This is part of improving floating-point patterns seen in:
https://llvm.org/PR39480
We don't require any FMF because the 2 potential corner cases
(-0.0 and NaN) are correctly handled without FMF:
1. -0.0 is treated as strictly less than +0.0 with
maximum/minimum, so fabs/fneg work as expected.
2. +/- 0.0 with maxnum/minnum is indeterminate, so
transforming to fabs/fneg is more defined.
3. The sign of a NaN may be altered by this transform,
but that is allowed in the default FP environment.
If there are FMF, they are propagated from the min/max call to
one or both new operands which seems to agree with Alive2:

[InstCombine] intersect FMF when reassociating FP min/max intrinsics
As discussed in PR45478:
https://bugs.llvm.org/show_bug.cgi?id=45478
...propagating FMF from the outer (second) call is not correct,
so intersect them instead.
I suspect we could do better (see TODO comment), but mismatched
FMF is probably too rare to care about.
