This will simplify the SGPR spilling and also allow us to use MachineFrameInfo for calculating offsets, which should be more reliable than our custom code. This fixes a crash in some cases where a register would be spilled in a branch such that the VGPR defined for spilling did not dominate all the uses when restoring. This fixes a crash in an ocl conformance test. The test requries register spilling and is too big to include. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216217 91177308-0d34-0410-b5e6-96231b3b80d8
