    cplus_demangle_fill_component: Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE
    
    This patch almost a decade ago:
    
    ...
        2007-08-31  Douglas Gregor  <doug.gregor@gmail.com>
    
            * cp-demangle.c (d_dump): Handle
            DEMANGLE_COMPONENT_RVALUE_REFERENCE.
            (d_make_comp): Ditto.
    ...
    
    ... missed doing the same change to cplus_demangle_fill_component that
    was done to d_make_comp.  I.e., teach it to only validate that we're
    not passing in a "right" subtree.  GDB has recently (finally) learned
    about rvalue references, and a change to make it use
    cplus_demangle_fill_component more ran into an assertion because of
    this.
    
    (GDB is the only user of cplus_demangle_fill_component in both the gcc
    and binutils-gdb trees.)
