tree-vrp.c (op_with_constant_singleton_value_range): New function.

2008-08-20  Richard Guenther  <rguenther@suse.de>

* tree-vrp.c (op_with_constant_singleton_value_range): New function.
(extract_range_from_binary_expr): Fall back to constant propagation.
(extract_range_from_unary_expr): Likewise.

* gcc.dg/tree-ssa/pr21829.c: Scan optimized and cddce2 dumps
instead of phicprop2.  Make sure all is fine after cddce2,
add an XFAILed scan for merging the two remaining ifs.
