The whole patch passed testing, but in the C++ FE (the cp/decl.c) it is
probably just a partial fix or even wrong fix (e.g., even when we don't
allocate a new cfun there, we still overwrite cfun->language with newly
GCed memory, etc.

So I'm going to commit now the tree.c and trans-decl.c hunks and
will leave the rest for later.
