Representation of and template instantiation for member

expressions. This change introduces another AST node,
CXXUnresolvedMemberExpr, that captures member references (x->m, x.m)
when the base of the expression (the "x") is type-dependent, and we
therefore cannot resolve the member reference yet.

Note that our parsing of member references for C++ is still quite
poor, e.g., we don't handle x->Base::m or x->operator int.
