[PATCH] D66827: Add support for MS qualifiers __ptr32, __ptr64, __sptr, __uptr.

Herald added projects: clang, LLVM.

Previously, these qualifiers were being parsed but otherwise ignored.
This change makes it so that an address space is added to specify whether the pointer is
32-bit or 64-bit and whether it is sign extended or zero extended.

In the backend, the address space casts are lowered to the corresponding
sign/zero extension or truncation.

The data layout for the address spaces was changed in https://reviews.llvm.org/D64931
