With bytecode flushing and lazy feedback allocation, we need to call
%PrepareForOptimization before we call %OptimizeFunctionOnNextCall,
ideally after declaring the function.

When TurboFan optimizes field access, we need to check first that the
runtime already determined the correct field representation properly.
If the field representation is still None, we cannot optimize this in
TurboFan straight away but we have to call the IC to let the runtime
do the magic.
