    gccrs: Unit struct constructor shall be resolved
    
    Unit struct have a special constructor that should be added to the struct
    namespace in order to be resolved later when called. As it is a function
    it should be added in the value namespace.
    
    gcc/rust/ChangeLog:
    
            * resolve/rust-toplevel-name-resolver-2.0.cc 
(GlobbingVisitor::visit):
            Add the struct constructor when the struct is a unit.
