When narrowing stores of a single-scalar, we currently use
ExtractLastElement, which extracts the last element across all parts.
This is not correct if the store's address is not uniform across all
parts. If it is only uniform-per-part, the last lane per part must be
extracted. Add a new ExtractLastLanePerPart opcode to handle this
correctly. Most transforms apply to both ExtractLastElement and
ExtractLastLanePerPart, with the only difference being their treatment
during unrolling.
