ir_to_mesa: Generate smarter code for some conditional moves

Condiation moves with a condition of (a < 0), (a > 0), (a <= 0), or (a
>= 0) can be generated with "a" directly as an operand of the CMP
instruction.  This doesn't help much now, but it will help with
assembly shaders that use the CMP instruction.
