R600/SI: Add a stub GCNTargetMachine This is equivalent to the AMDGPUTargetMachine now, but it is the starting point for separating R600 and GCN functionality into separate targets. It is recommened that users start using the gcn triple for GCN-based GPUs, because using the r600 triple for these GPUs will be deprecated in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225277 91177308-0d34-0410-b5e6-96231b3b80d8

R600/SI: Add load / store machine optimizer pass. Currently this only functions to match simple cases where ds_read2_* / ds_write2_* instructions can be used. In the future it might match some of the other weird load patterns, such as direct to LDS loads. Currently enabled only with a subtarget feature to enable easier testing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219533 91177308-0d34-0410-b5e6-96231b3b80d8
