Add a utility function that detects whether a loop is guaranteed to be finite.

Use it to safely handle less-than-or-equals-to exit conditions in loops. These

in the exit condition.

Avoid using a loop in ReleasePred and ReleaseSucc methods to compute the
...
new CycleBound value. Instead, just update CycleBound on each call.
Also, make ReleasePred and ReleaseSucc methods more consistent accross
the various schedulers.
This also happens to make ScheduleDAGRRList's CycleBound computation
somewhat more interesting, though it still doesn't have any noticeable
effect, because no current targets that use the register-pressure
reduction scheduler provide pipeline models.
