re PR middle-end/34070 (Wrong code for (int)x%4)

2007-11-12  Richard Guenther  <rguenther@suse.de>

PR middle-end/34070
* fold-const.c (fold_binary): If testing for non-negative
operands with tree_expr_nonnegative_warnv_p make sure to
use op0 which has all (sign) conversions retained.

* gcc.c-torture/execute/pr34070-1.c: New testcase.
* gcc.c-torture/execute/pr34070-2.c: Likewise.
