-- Calling "x86_alu_reg8_reg8 _ _ _ *False* *False*" is a little bit hackish: the last two
-- arguments are set to True for the "high byte registers" ah, bh, ch and dh.
-- x86_reg8_emit then sets the 3rd bit in the register number. This bit is set in our
-- encoding anyway to the right value, so we simply skip this part.
