This patch is a rewrite of the original patch commited in r194542. Instead of relying on the type legalizer to do the splitting for us, we now peform the splitting ourselves in the DAG combiner. This is necessary for the case where the vector mask is a legal type after promotion and still wouldn't require splitting. Patch by: Juergen Ributzka NOTE: This is a candidate for the 3.4 branch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195397 91177308-0d34-0410-b5e6-96231b3b80d8
