c++: Parser tweaks
We need to adjust the wording for 'export'. Between c++11 and c++20
it is deprecated. Outside those ranges it is unsupported (at the
moment). While here, there's also an unneeded setting of a bool --
it's inside an if block that just checked it was true.
gcc/cp/
* parser.c (cp_parser_template_declaration): Adjust 'export' warning.
(cp_parser_explicit_specialization): Remove unneeded bool setting.
