[issue11816] Refactor the dis module to provide better building blocks for bytecode analysis

[Nick Coghlan]

I have updated my BitBucket repo with the following changes:

- the main API is now dis.get_instructions()
- the info class is now dis.Instruction
- get_instructions() accepts a 'line_offset' argument that is added to any source code line numbers
- the printing of individual lines in all the disassembly operations is now handled by a private Instruction._disassemble() helper method
- assertBytecodeExactlyMatches now relies on the list comparison machinery in unittest, as well as the Instruction.__eq__ implementation provide by collections.namedtuple (this gives *much* better error messages when discrepancies are found)
- to further improve error messages reported by unittest (which can truncate representations), the order of the Instruction fields now has 'opname' first, then 'opcode', then the remaining fields.
