Rethinks size
; packs all captured information into an x86 Instruction.
...
Albeit that operand and displacement are't yet captured. Or extractable.

Starts trying to find a good packing for X86 instructions.
...
To consider: do I really need `size` on every instruction?

Fills in 8f, c2, c3, ca and cb.
...
Also switches to RETN and RETF for near/far RET as this seems idiomatic.

Ostensibly gets the instruction stream correct for test case 1.
...
Subject to operand and displacement currently being absent, and likely inconsistencies in field population, most of which are omitted from the Instruction anyway.
