Fixes 11

[BDanAnd]

The main goal is to change the algorithm for building instructions tree.

v4

• reorder and squash commits

v3.1

• shorten new CLI opts
• rename InfixIntervalsContainer -> InfixSet and base on intervalmap

v3:

• fixup misprints
• add GUI option and CLI flag --disable-cpu-semantics-translation to disable I3S translation
• add InfixIntervalsContainer class to manage intervals
• add a comment to the generated source code with values that are covered by the default case

v2.1:

• build_instruction_tree_test do process all examples and random instructions sets

v2:

• fixup and add comments
• use zip_longest instead of zip in InstructionTreeNode.__eq__
• divide print_instructions function into print_instructions and format_instructions functions
• add used attribute to class Instruction permanently
• move optimizations code from build_instruction_tree function into a separate optimize_instruction_subtree function
• add CLI flag --disable-instruction-tree-optimizations to disable optimizations
• use insort instead of linear insertion algorithm in optimize_instruction_subtree
• add examples for instruction tree optimizations
• add TreeStats for storing tree statistics
