[ValueTracking][InstCombine] restrict FP min/max matching to avoid miscompile
This is a long-standing FIXME with a non-FMF test that exposes
the bug as shown in issue #57357.
It's possible that there's still a way to miscompile by
mis-identifying/mis-folding FP min/max patterns, but
this patch only exposes a couple of seemingly minor
regressions while preventing the broken transform.
