Both POW and INT DIV need a message length of 2; previously, we only checked for POW. Also, BRW_MATH_FUNCTION_INT_DIV_QUOTIENT_AND_REMAINDER has a response length of 2; previously, we only checked for SINCOS. We don't use this message, but in case we ever decide to, we may as well fix it now. While we're at it, just move these computations into brw_set_math_message, since they're entirely based on the function. This fixes it for both brw_math and the old backend's brw_math_16.
