This is already performed in InstCombinerImpl.visitCallInst - but this occurs AFTER vector-combine has run, so further cost driven vector-combine shuffle folds are missed.
We should only need to handle vector_insert calls with FixedVectorTypes and there might not be any reason for a cost check, but we must ensure the shuffle are added back to the worklist to allow further expansion.
