Make it possible to print Michelson comments from Lorentz/Indigo
Clarification and motivation
Sometimes it is hard to understand what code is produced from Indigo/Lorentz (especially for Indigo). But it's very useful when you want to optimize code generator or if you encounter something weird.
Acceptance criteria
Lorentz and Indigo should have instructions using which one can insert comments into produced Michelson.
