[PATCH] D61756: Add a __FILE_NAME__ macro.

Landing this as discussed on IRC, will try to push it forward with WG14.

I think having something like this as part of the standard would benefit a lot, since currently the "unofficial" way of doing this for either GCC or Clang involves several nonstandard builtins and `__FILE__` which causes difficulties in reproducible builds as code emitted in read only data sections may still differ depending on optimization levels and other factors. This macro on the other hand provides a guarantee that only the last path component is rendered.

  rC Clang
