Fixes #68270 The function attribute analysis handles many instructions, like addrspacecast, which do not themselves read or write memory but which transform pointers into other values in the same alias set. There are intrinsic functions, such as ptrmask or the AMDGPU-specific make.buffer.rsrc, which also preserve membership in alias sets without capturing. This commit adds the addrspacecast-like behavior to these calls.
