[SLPVectorizer] shouldReorderOperands - just check for reordering. NFCI.

Remove the I.getOperand() calls from inside shouldReorderOperands - reorderInputsAccordingToOpcode should handle the creation of the operand lists and shouldReorderOperands should just check to see whether the i'th element should be commuted.
