AMDGPU: Fix verifier error from partially undef copy In this situation: %VGPR2<def> = BUFFER_LOAD_DWORD_OFFSET %SGPR8_SGPR9_SGPR10_SGPR11, %VGPR7<def,tied3> = V_MAC_F32_e32 %VGPR0<undef>, %VGPR1<kill>, %VGPR7<kill,tied0>, %EXEC<imp-use> %VGPR3_VGPR4_VGPR5_VGPR6<def> = COPY %VGPR0_VGPR1_VGPR2_VGPR3 %VGPR4<def> = COPY %VGPR2 The copy for VGPR1 -> VGPR4 was an error from reading undefined VGPR1, but VGPR4 is defined immediately after this copy. llvm-svn: 275635
