    Use rust_demangle to fix a crash

    PR rust/30211 points out a crash caused by a particular completion.
    This turns out to happen because a Rust minsym winds up in a
    C++-specific path in strncmp_iw_with_mode, which ultimately causes the
    completer to pass invalid arguments to string::append.

    This patch fixes the bug by reordering the language constants so that
    Rust comes before C++, and then using rust_demangle.  This ensures
    that minsyms are correctly marked as "Rust", avoiding this code and
    thus the crash.
