An analysis of real world code turned up a number of patterns with BUILD_VECTOR of nodes resulting from operations on extracted vector elements for which we produce poor code. This addresses those cases. No attempt is made for completeness as that would entail a large amount of work for something that there is no evidence of in real code.
