0b6db777 - [AMDGPU] Handle AV classes in SIFixSGPRCopies::processPHINode (#169038)

[AMDGPU] Handle AV classes in SIFixSGPRCopies::processPHINode (#169038) Fix a problem exposed by #166483 using AV classes in more places. `isVectorRegister` only accepts registers of VGPR or AGPR classes. `hasVectorRegisters` additionally accepts the combined AV classes. Fixes: #168761
