ishell 4a5446fb2b [tests] Make assertOptimized()/assertUnoptimized() great again.
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.
