Doug Gregor 82de47c494 [Macros] Fix name lookup in macro expansion declaration arguments. ...

Teach ASTScope to create child nodes for each of the arguments of a
macro expansion declaration, so that we can perform name lookup into
them. Otherwise, we cannot have nontrivial closures in arguments to a
macro expansion declaration.

Fixes rdar://107388151.
