[PATCH] D37035: Implement __builtin_LINE() et. al. to support source location capture.

[Eric Fiselier via Phabricator via cfe-commits]

- Reimplement without rewriting the AST and instead during the substitution during constant expression evaluation and code gen.

I still haven't implemented Richards suggestion to reduce the size of `source_location` struct, but I think that would be better done as a separate patch. These builtins still need to be implemented, and to act like their GNU counterparts.

I haven't cleaned this patch up yet, but I plan to do so tomorrow. There are going to be silly mistakes until then.
