eb35ade9a0 6232281: -XX:-UseLoopSafepoints causes assert(v_false,"Parse::remove_useless_nodes missed this node") 
Check for nodes missed by remove_useless_nodes() only if PhaseRemoveUseless has
actually been run. This makes it possible to use -XX:-UseLoopSafepoints without
crashing trivially, although implicit assumptions in other parts of C2 about the
existence of loop safepoints might lead to more subtle failures for more complex
methods.
