Actually moving any of remaining optimizations (including two optimizations that are moved by this issue and two other that are left) slightly increases the complexity. But instead the optimizations become more general. At the end, after moving all optimizations, we could drop the auxiliary code in the peepholer (building the table of basic blocks, removing NOPs, fixing up jump targets) and the net complexity will be reduced. This can also reduce the time and memory consumption of compilation.

Thus getting rid of the peepholer optimizer working with the bytecode is my goal. But some peephole optimizations will work with the intermediate fixed-size representations used by the compiler, before generating the concrete bytecode.
