[Mesa-dev] [PATCH 0/4] i965: use SSA values when we can

Before, we were using a hack where when we converted out of SSA, we set a "parent_instr" field of the nir_register to indicate that the register was actually an SSA value. But in the future, we want to handle SSA values directly, and right now we're creating an extra nir_register for everything, ev
