patch we add a flag to enable a new type legalization decision - to promote integer elements in vectors. Currently, the rest of the codegen does not support this kind of legalization. This flag will be removed when the transition is complete. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132394 91177308-0d34-0410-b5e6-96231b3b80d8
