Support for __LINE__ and __FILE__ in preprocessor (#1772)
* #include an absolute path didn't work - because paths were taken to always be relative. * First pass support for __LINE__ and __FILE__. * Test include handling with __FILE__ Fix diagnostic compare when input is empty. * Fix some issues in preprocessor handling of special macros like __LINE__ Add a more complex test. * Use CONCAT2 in tests, because preprocessor doesn't quite get parameter expansion correct. * Make __FILE__ and __LINE__ behave more like Clang/Gcc. * A test for preprocessor bug. * Fix __LINE__ and __FILE__ in macro expansion, should be initiating location. * Fix some comments. * Small tidy up around builtin macros. * Small improvements for macro type names. Escape found paths.
