  Log Message:
  -----------
  [NVPTX] Add support for Shared Cluster Memory address space [1/2] (#135444)

Adds support for new Shared Cluster Memory Address Space
(SHARED_CLUSTER, addrspace 7). See
https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#distributed-shared-memory
for details.

1. Update address space structures and datalayout to contain the new
space
2. Add new intrinsics that use this new address space
3. Update NVPTX alias analysis

The existing intrinsics are updated in
https://github.com/llvm/llvm-project/pull/136768
