  [SLP][modularisation][NFC] Move reduction match helpers to SLPReductionUtils (#222052)

Move the following BoUpSLP-independent reduction pattern-match helpers
out of SLPVectorizer.cpp into a new
SLPVectorizer/SLPReductionUtils.{h,cpp}:

  getNonPhiOperand
  isReductionCandidate

matchRdxBop, used only by these two, moves alongside them and stays
file-local. Behavior is unchanged.

Part of the SLPVectorizer.cpp modularization effort:
