trinary operation!

ADD_r_x_x
ADD_x_r_x
ADD_x_x_r
ADD_x_r_r
ADD_r_x_r
ADD_r_r_x
ADD_r_r_r
(x: not relative addressing, r: relative addressing)
Alternatively, the code selector could be designed to generate 'mov'
instruction with relative addressing only. The above 'add' instruction
is translated to:
mov r1, r[a0]
