R600/SI: Implement areLoadsFromSameBasePtr 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

declare i32 @llvm.r600.read.tidig.x() #1
; FIXME: This currently doesn't do a great job of clustering the
; loads, which end up with extra moves between them. Right now, it
; seems the only things areLoadsFromSameBasePtr is accomplishing is
; ordering the loads so that the lower address loads come first.
