A much simplified version of D17741 <https://reviews.llvm.org/D17741> which adds a new builtin macro `__FILE_NAME__` that is similar to `__FILE__` but only renders the last path component. It seems that this functionality is highly desired from the consensus on D17741 <https://reviews.llvm.org/D17741> as a separate macro versus a much more complicated and niche patch originally proposed in that differential.
