Log:
        PR c++/91673 - ICE with noexcept in alias-declaration.
        * parser.c (CP_PARSER_FLAGS_DELAY_NOEXCEPT): New parser flag.
        (cp_parser_lambda_declarator_opt): Pass CP_PARSER_FLAGS_NONE to
        cp_parser_exception_specification_opt.
        (cp_parser_direct_declarator): Adjust a call to
        cp_parser_exception_specification_opt.
        (cp_parser_member_declaration): Pass CP_PARSER_FLAGS_DELAY_NOEXCEPT
        to cp_parser_declarator if not processing a friend or typedef
        declaration.
        (cp_parser_late_noexcept_specifier): Adjust a call to
        cp_parser_noexcept_specification_opt.
        (cp_parser_noexcept_specification_opt): New parameter for parser flags,
        drop the FRIEND_P parameter.  Use the new parameter.
        (cp_parser_exception_specification_opt): Likewise.
        (cp_parser_transaction): Adjust a call to
        cp_parser_noexcept_specification_opt.
        (cp_parser_transaction_expression): Likewise.
