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

We cannot just blindly make a representation selection for Phi or Select
based on the truncations, but we also need to consider the type of the
inputs (or actually of the Phi/Select node itself). We can only use
Word32 representation based on Word32 truncation if the inputs are
Number or Oddball, same for Float64.
