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.

fed3636f12 8252219: C2: Randomize IGVN worklist for stress testing 
Add 'StressIGVN' option to let C2 randomize IGVN worklist order. When enabled,
the worklist is shuffled before each main run of the IGVN loop. Also add
'StressSeed=N' option to specify the seed. If the seed is not specified, a
random one is generated. In either case, the seed is logged if 'LogCompilation'
is enabled. The new options are declared as production+diagnostic for
consistency with the existing 'StressLCM' and 'StressGCM' options.
