* cp-names.y (LONGEST, ULONGEST, DOUBLEST): Remove.

	(d_qualify): Take an int argument.  Update for new INT_LLONG
	handling.
	(INT_CHAR, INT_SHORT, INT_LONG, INT_LLONG, INT_SIGNED)
	(INT_UNSIGNED): Change into bitflags.
	(%union): Change lval and typed_val_int.val to ints.
	(scope_id, typespec): Inline non-terminals at their use sites.
	(sign, size, int_type): Remove.
	(int_part, int_seq): New non-terminals.
	(result): Add missing semicolon.
	(name, nested_name): Inline scope_id here.
	(template_arg, function_args): Inline type here.
	(builtin_type): Use int_seq.  Add missing semicolon.

	(abstract_declarator_fn): Likewise.
	(d_builtin_type): New helper function.
	(parse_number): Use d_builtin_type.
	(HANDLE_SPECIAL): Only take one argument.
	(yylex): Remove unused variable unquoted_expr.  Use d_builtin_type.
	Update calls to HANDLE_SPECIAL.  Jump around case '-' instead of
	falling through it.  Use ISALNUM and ISALPHA.  Add a return
	statement after a call to error.  Match trailing speaces on special
	tokens.
	(cp_print): Take a len argument, and pass it to d_print.  Print the
