[AMDGPU] Improve llvm.amdgcn.wave.shuffle handling for pre-GFX8 (#174845)
Before, GlobalISel would still return true for lowering the intrinsic
for GFX7 and earlier even though the required ds_bpermute_b32
instruction is not supported. After this change, GlobalISel will
properly report failure to select in this case. Testing is updated
appropriately.
