Log Message:
-----------
DFGOSRAvailabilityAnalysis phase should only assert liveness of arguments
during validation pass

Reviewed by Dan Hecht.
It is incorrect to assert liveness while we are still converging to fixpoint;
we should only assert once we've converged to fixpoint. This fix ensures that
we only check that arguments are live to calls when we have reached fixpoint.
