Implement libclang visitation for UnresolvedMemberExpr. This is the

last of the C++-specific expressions where we have decent source
information in the AST already. In particular, various
object-construction expressions (CXXNewExpr, CXXTemporaryObjectExpr)
still have poor source-location information that needs to be addressed.
