v8/test/mjsunit/deopt-recursive-lazy-once.js
Mythri 7371c34b6b Use --opt instead of --crankshaft in tests.
1. Replaces --crankshaft with --opt in tests.
2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and 
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.
