ANY/ALL/NONE have been temporarily removed until I implement the HOPS (horizontal operations) sub-instructions, which will all both 32-bit and 64-bit operands and several other operations (eg, horizontal add). All the fancy addressing modes for the conditional branch instructions have been permanently removed: I decided the gain was too little for the cost (24 instructions vs 6). JUMP and CALL retain their addressing modes, though. Other instructions have been shuffled around a little to fill most of the holes in the upper block of 256 instructions: just a single small 7-instruction hole. Rearrangements in the actual engine are mostly just to keep the code organized. The only real changes were the various IF statements and dealing with the resulting changes in their addressing.
