The test whether a movz instruction with a signed immediate should be turned into a movn instruction (i.e., when the immediate is negative) is flawed, since the value of imm is always positive. Also, the subsequent bounds check is incorrect since the limit update never executes, due to the fact that the imm_type comparison will always be false for negative signed immediates. Let's fix this by performing the sign test on sval directly, and replacing the bounds check with a simple comparison against U16_MAX.
