[PATCH] D53708: [ASTImporter] Add importer specific lookup

[Gabor Marton via Phabricator via cfe-commits]

martong added a comment.

Constructs like `struct A { struct Foo *p; };` are very common in C projects. Since `Foo` as a forward decl cannot be found by normal lookup we need this patch in order to properly CTU analyze even a simple C project like `tmux`.
