[PATCH] D49554: [APInt] Keep the original bit width in quotient and remainder

Some trivial cases in udivrem were handled by directly assigning 0 or 1 to APInt objects. This would set the bit width to 1, instead of the bit width of the inputs. A potentially undesirable side effect of that is that with the bit width of 1, 1 equals -1.
