Simon Pilgrim f36ee139a4 [SLPVectorizer] Merge reorderAltShuffleOperands into reorderInputsAccordingToOpcode
As discussed on D59738, this generalizes reorderInputsAccordingToOpcode to handle multiple + non-commutative instructions so we can get rid of reorderAltShuffleOperands and make use of the extra canonicalizations that reorderInputsAccordingToOpcode brings.
