Set language for C++ special symbols.

	Set language for C++ special symbols.

The special handling of C++ special symbol
generates symbols that have no language.
Those symbols cannot be displayed correctly in the backtrace stack.

See
https://sourceware.org/bugzilla/show_bug.cgi?id=17811
for details and examples in C++ and pascal language.

The patch below fixes this issue, by
setting language of new symbol before
special handling of special C++ symbols.
