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

Reading the registers' values back from the FrameDescription
should use the same offset computation as storing them into it.
The offsets must also match what the deoptimizer expects, which
is rx at offset rx.code() * kDoubleSize, even if some registers
are not saved (leaving gaps).
