Subject: [PATCH] When expanding a vector_shuffle, the element type may not be
 legal and may need to be promoted.  The BUILD_VECTOR and EXTRACT_VECTOR_ELT
 nodes generated here already allow the promoted type to be used without
 further changes, so just do the promotion.  This fixes part of pr7167.
