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.

Hi.
LGTM with two nits:
1) A blank line after the SYMBOL_SET_LANGUAGE call would
block the code better to this reader.
2) I believe convention is to remove the "Fix for" in the changelog entry.

Thanks,
for the record, below is what I committed.
I hope it takes your nits correctly into account.
