* pt.c (check_explicit_specialization): If DECLARATOR turned into
an error_mark_node from lookup_template_function, return the same.
(determine_specialization): Also make sure TEMPLATE_ID isn't an
error_mark_node, before we try to read its operands.
* decl.c (grokdeclarator): If we got an error_mark_node from
check_explicit_specialization, just return it right back.
