[PATCH] D142934: clang: Use ptrmask for pointer alignment

[Alexander Richardson via Phabricator via cfe-commits]

arichardson added a comment.

The `__builtin_align_{up,down}` code generation could also make use of this IIRC. I think the reason I didn't do this initially was concerns about ptrmask not being optimized as well.
