The SelectionDAGBuilder was promoting vector kernel arguments to legal types, but this won't work for R600 and SI since kernel arguments are stored in memory and can't be promoted. In order to handle vector arguments correctly we need to look at the original types from the LLVM IR function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193215 91177308-0d34-0410-b5e6-96231b3b80d8
