Using 386+ opcodes in asm ... end blocks is a PITA, so for those 1/2/4 byte
opcodes that I use regularly, I have set up constants. They allow me to use
them in a more readable

asm
  dd  instruction_constant
end

fashion.

Below is a list of the ones I've used sofar, maybe others can contribute
more, I would especially be interested in MMX opcodes, as TD is a bit to old
to create these.
