- In last https://reviews.llvm.org/D69826, generic pointers in struct/array types are also replaced with global pointers. But, as no additional `addrspacecast` is inserted, they are promoted with a `ptrtoint`/`inttoptr` pair in SROA/GVN. That breaks the address space inferring as well as other optimizations. For such case, we need to recursively dive into these aggregate types and insert `addrspacecast` when necessary.
