The problem is, there exists only bytecode disassembler, no corresponding

Why would you like to work on bytecode instead of AST? The AST
contains much more information, you can implement better optimizations
AST allows for better high-level optimizations, but a real peephole
optimization pass is actually designed to optimize generated code. This
allows eliminating some inefficiencies which would be fairly hard to
prevent at higher levels - wikipedia provides some examples.
