tree-optimization/125040 - iterate PRE clean

The testcase has a cycle in the value graph of ANTIC_IN, this means
we have to iterate to correctly prune all invalid expressions.

	PR tree-optimization/125040
	* tree-ssa-pre.cc (clean): Iterate processing.

	* gcc.dg/torture/pr125040.c: New testcase.
