  -----------
  [IVDescriptor] Explicitly check for isMinMaxRecurrenceKind in getReductionOpChain. NFC (#132025)

There are other types of recurrences with an icmp/fcmp opcode, AnyOf and
FindLastIV, so don't rely on the opcode to detect them.
This makes adding support for AnyOf in #131830 easier.

Note that these currently fail the ExpectedUses/isCorrectOpcode checks
anyway, so there shouldn't be any functional change.
