Perf if all bytecodes are 32bits

[stevehalliwell]

What if we made all opcodes 32bits, no more no less, if you don't want the extra bytes, ok enjoy your zeros.

Should be easier to move through and rewrite and move around. Makes bytecode iteration trivial.

It is noticeably slower, but marginally so.

Compiling code is considerably less complicated, and allows for registers to be used for local operations. Since the add is now add 0,0,0, which could become registered bytes.
