6f7c77fe - [AMDGPU] Check noalias.addrspace in mayAccessScratchThroughFlat (#151319)

[AMDGPU] Check noalias.addrspace in mayAccessScratchThroughFlat (#151319) PR #149247 made the MD accessible by the backend so we can now leverage it in the memory model. The first use case here is detecting if a flat op can access scratch memory. Benefits both the MemoryLegalizer and InsertWaitCnt.
