Revert "Sync libiberty sources with master version in gcc repository. Updated stabs demangling and cxxfilt tests to match." 

The previous commit breaks the GDB build, which is still using functions
cplus_demangle_opname & co.  Since removing these usages is not an
obvious fix, let's revert this patch until we get rid of them.
