    gccrs: Add mappings for struct base and struct fields
    
    Definition/usage mapping during name resolution was missing.
    
    gcc/rust/ChangeLog:
    
            * resolve/rust-late-name-resolver-2.0.cc (Late::visit): Add mapping
            implementation.
            * resolve/rust-late-name-resolver-2.0.h: Add function visitor 
prototype
            override.
