    gccrs: Resolved item type shall be differentiated later
    
    We need to query all namespaces and error out at a later stage if the
    retrieved item is wrong.
    
    gcc/rust/ChangeLog:
    
            * typecheck/rust-hir-trait-resolve.cc 
(TraitResolver::resolve_path_to_trait):
            Query all namespaces.
