cpphash.c (collect_objlike_expansion): Add sanity check.

* cpphash.c (collect_objlike_expansion): Add sanity check.
(special_symbol): Remove case T_CONST, T_XCONST, T_MCONST.  If
the buffer is the empty string, return.  Mark __DATE__ and
__TIME__ as XCONST nodes, not MCONST.
(_cpp_macroexpand): Avoid pushing an empty buffer.
(funlike_macroexpand): Don't pop token_buffer here.
