Jay Foad 38302c60ef [AMDGPU] Stop looking for implicit M0 uses on MOV instructions 
Before D114230, indirect moves used regular MOV opcodes and were
identified by having an implicit use of M0. Since D114230 they use
dedicated opcodes instead, so remove some old code that checks for
implicit uses of M0. NFCI.
