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.
