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.
