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.
