[PATCH] D17741: adds __FILE_BASENAME__ builtin macro

[Nolan O'Brien via Phabricator via cfe-commits]

NSProgrammer added a comment.

We would prefer a macro like `__FILE_NAME__` over a build flag for code reading consistency (they would clearly do different things vs varying based on an obscure flag being present/absent).

This patch is languishing, unless the original author thinks otherwise, a new patch to push this through would be great.
