clang-p2996/llvm/test/CodeGen/AMDGPU/remat-sop.mir
Stanislav Mekhanoshin 6185835656 [AMDGPU] Allow rematerialization of SOP with virtual registers 
D106408 was doing this for all targets although it was
reverted due to couple performance regressions on some targets.
The difference for AMDGPU is the ability to rematerialize SOP
instructions with virtual register uses like we already do for VOP.
