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.
