Michael Achenbach 8140856013 [foozzie] Add sanity check for missing natives suppression 
This prevents bug flooding based on differences from calling
%GetOptimizationStatus in correctness tests. It is supposed to
be suppressed with --allow-natives-for-differential-fuzzing.
This ensures early bail-out in case the flag is forgotten at
some point. The v8_sanity_checks.js file is executed before
each correctness test case for this purpose.
