This patch is what was the "instcombine" portion of [[ http://reviews.llvm.org/D14185 | D14185 ]], with an additional test added  (see julia_pseudovec in test/Transforms/InstCombine/insert-val-extract-elem.ll).  The patch causes instcombine to replace sequences of extractelement-insertvalue-store that act essentially like a bitcast followed by a store.
