  Log Message:
  -----------
  [LoopUtils] do not initialize Cmp predicate unnecessarily; NFC

The switch must set the predicate correctly; anything else
should lead to unreachable/assert.

I'm trying to fix FMF propagation here and the callers,
so this is a preliminary cleanup.

  Log Message:
  -----------
  [LoopVectorize] add test for fmin/fmax FMF propagation; NFC

The existing test has less FMF than we might expect if
our FMF was fixed (on all FP values), so this additional
test is intended to check propagation in a more "normal"
example.
