Some fixes to type-visiting -- a few places where the type-name was

explicitly typed in the source, but we weren't recursing on it.  One
is new <type>, the other is <type>() (eg int()).

I also fixed the initializer parsing to parse on the syntactic
initializer list, not the semantic.  Usually they'll be identical, so
this won't affect much in practice, but keeps the AST as a syntax-tree
visitor.
