The mentioned asserts did not work properly with interpreted and turbofanned functions. To fix this issue %GetOptimizationStatus() now returns a set of flags instead of a single value. This CL also adds more helper functions to mjsunit, like isNeverOptimize(), isAlwaysOptimize(), isOptimized(fun), etc. BUG=v8:5890 Review-Url: https://codereview.chromium.org/2654733004 Cr-Commit-Position: refs/heads/master@{#42703}
