    gccrs: Move debug-related functions into base class Backend
    
    gcc/rust/ChangeLog:
    
            * rust-backend.h
            (Backend::debug): Make non-virtual.
            (Backend::get_identifier_node): Likewise.
    
            (Gcc_backend::debug): Remove.
            (Gcc_backend::get_identifier_node): Remove.
            * rust-gcc.cc
            (Gcc_backend::debug): Rename to ...
            (Backend::debug): ... here.
            (Gcc_backend::get_identifier_node): Rename to ...
            (Backend::get_identifier_node): ... here.
