Fix PR2355: bug in ChangeCompareStride. When the loop termination compare is the only use of its iv stride, the stride can be eliminated by moving it to another stride. If the scale is negative, swap the predicate instead of using a inverse predicate.

Fix a bug in LSR's dead-PHI cleanup. If a PHI has a def-use chain that
...
leads into a cycle involving a different PHI, LSR got stuck running
around that cycle looking for the original PHI. To avoid this, keep
track of visited PHIs and stop searching if we see one more than once.
This fixes PR2570.

Refine the change in r52258 for avoiding use-before-def conditions

when changing the stride of a comparison so that it's slightly

if there is a use of the condition after the point where the
condition will be inserted.
