v8/test/mjsunit/debug-evaluate-locals-optimized.js
erik.corry@gmail.com 292e007cf3 Remove more assumptions from debug tests. Even though a function
is optimized, does not mean all frames on the stack are optimized.
Also, when we ask for the list of scripts we may get more or less
depending on GC timing.  Also fixed a presubmit error and made
%GetOptimizationStatus a little more honest.
