[PATCH] D14286: ASTImporter: expressions, pt.1

Thank you for your comments. I leaved some replies and will update revision.
Something about lacking tests.

1. We cannot check if expression import is correct until we implement FunctionDecl body import. I was going to upstream Decl-related parts later but maybe it is better to include this small case in the first patch. What do you think?
2. What is the best way to test import of statements? Currently I have no idea how to do this (except of ast-dump). Any suggestions are welcome.

Ouch. I was just trying to unify this with the code already existing in ASTImporter. I'll rename this.
// TODO: refactor std::transform usage in ASTImporter.

I'll use it in later patches so I'd prefer to keep it.

This guard is here because the return result of import may be null. This cast_or_null (and some others) handles such cases.
