  -----------
  [SLP] separate min/max matching from its instruction-level implementation; NFC

The motivation is to handle integer min/max reductions independently
of whether they are in the current cmp+sel form or the planned intrinsic
form.

We assumed that min/max included a select instruction, but we can
decouple that implementation detail by checking the instructions
themselves rather than relying on the recurrence (reduction) type.
