Make cache information a part of dis.Instruction

[iritkatriel]

Feature or enhancement

We currently create fake Instruction objects to represent cache entries. It would make more sense to make the cache info part of the Instruction.

This will change the output of dis.get_instructions, but not anything which is documented.
