libstdc++: Deliver names of C functions in <stacktrace>
__cxa_demangle is only to demangle C++ names, for all C functions,
extern "C" functions, and including main it returns -2, in that case
just adapt the given name. Otherwise it's kept empty, which doesn't look
nice in the stacktrace.
libstdc++-v3/ChangeLog:
* include/std/stacktrace (stacktrace_entry::_S_demangle): Use
raw __name if __cxa_demangle could not demangle it.
