This patch enables combining integer bitcasts of integer build vectors when the new scalar type is legal. I've avoided floating point because the implementation bitcasts float to int along the way and we would need to check the intermediate types for legality Differential Revision: https://reviews.llvm.org/D58884 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@355324 91177308-0d34-0410-b5e6-96231b3b80d8
