  -----------
  [SPIRV] Add support for G_PTRMASK (#201450)

This instruction is generated by the
[llvm.ptrmask](https://llvm.org/docs/LangRef.html#llvm-ptrmask-intrinsic)
intrinsic, which is used for Clang builtins like
[__builtin_align_up](https://clang.llvm.org/docs/LanguageExtensions.html#alignment-builtins)
which is used in `libc`.

We are working on building `libc` for SPIR-V, so we hit this problem.
