AMDGPU: Cleanup subtarget features Try to avoid mutually exclusive features. Don't use a real default GPU, and use a fake "generic". The goal is to make it easier to see which set of features are incompatible between feature strings. Most of the test changes are due to random scheduling changes from not having a default fullspeed model. llvm-svn: 310258

Replace subregister uses when processing tied operands This was for some reason skipping operands that are subregisters instead of keeping the same subregister index. v_movreld_b32 expects src0 to be the subregister of the tied super register use/def. e.g. v_movreld_b32 v0, v9, <imp-def, tied3> v[0:3], <imp-use, tied2> v[0:3] was being replaced with v[4:7] = copy v[0:3] v_movreld_b32 v0, v9, <imp-def, tied3> v[4:7], <imp-use, tied2> v[4:7], which really writes to v[0:3] llvm-svn: 279804
