  -----------
  [clang][CUDA][Windows] Fix compilation error on Windows with `uint32_t __nvvm_get_smem_pointer`

The change fixes https://github.com/llvm/llvm-project/issues/54609 (the second reported issue) by eliminating a compilation error occurring only on Windows while trying to compile any CUDA source file by clang (-x cuda).

[Repro]
clang -x cuda <any_cu_source>
