    lto: use diagnostics_context in print_lto_docs_link
    
    Properly parse OPT_fdiagnostics_urls_ and then initialize both urls
    and colors for global_dc. Doing that we would follow the configure
    option --with-documentation-root-url, -fdiagnostics-urls is respected.
    Plus we'll print colored warning and note messages.

    gcc/ChangeLog:
    
            * lto-wrapper.cc (print_lto_docs_link): Use global_dc.
            (run_gcc): Parse OPT_fdiagnostics_urls_.
            (main): Initialize global_dc.
