[PATCH] D52795: [analyzer][PlistMacroExpansion] Part 3.: Macro arguments are expanded

[Umann Kristóf via Phabricator via cfe-commits]

Szelethus updated this revision to Diff 174074.
Szelethus added a comment.

- Added more documentation
- Changed the nullpointer semantics as @xazax.hun pointed out
- Realize that macro arguments themselves can be macros, handle them too.
- Add a bunch more test. The above point actually fixed a wrong macro expansion is `CALL_LAMBDA` that somehow didn't get noticed. Gotta pay more attention when making the test files.
