Hi,
this patch fixes an ICE happening on invalid code for < c++11. It is
reasoned by
accessing blindly identifier without checking that it is a declaration.

PR c++/64127
* parser.c (cp_parser_diagnose_invalid_type_name): Check
id for being a declaration before accessing identifier.
Tested on x86_64-unknown-linux-gnu.
Ok for apply?
Regards,
Kai
