Ryan Houdek 2eb7a9ff28 OpcodeDispatcher: Remove old bad assumption in INC/DEC 
Somewhere there was an assumption made that INC and DEC supported the
repeat prefix. This isn't actually the case, while the prefix can be
encoded, it is a nop and should only expect to be used for padding.

Adds a unittest to ensure that behaviour is as expected.
