Remove the distinction between wide and xwide instructions
Only keep 1 byte and 4 byte wide instructions. As this gives
less than 256 distinct instructions, those can now again be
encoded in 1 byte, dropping the Wide and XWide prefix instructions.
This gives us 95% of the size savings that we had before, by
being able to encode the full instruction in one byte, while
bringing back pretty much all of the speed lost through the
compression.
