Check if the frame is optimized before marking a function for optimization.
When checking for marking a function for optimization, we had a check if the function is already optimized to return early. This works in non-OSR cases. For Turbofan OSR even when the current execution of the function has already been optimized, the function itself will not be replaced with optimized code. Hence, we may end up checking a function that is already marked for optimization again. A check for the frame being optimized avoids these checks.
