    Add debug dump to old name resolver
    
    It might be necessary to compare both name resolution' internal states
    during the transition. This new debug representation could help with
    that.
    
    gcc/rust/ChangeLog:
    
            * resolve/rust-name-resolver.h: Add new degug dump for old name
            resolver.
