This currently has a noticable effect on the kernel argument loads. LDS and global loads are more problematic, I think because of how copies are currently inserted to ensure that the address is a VGPR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214942 91177308-0d34-0410-b5e6-96231b3b80d8
