Herald added a project: LLVM.

As discussed on D59738 <https://reviews.llvm.org/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.
