 bit_ceil(): let N be the smallest power of 2 greater than or equal to x [bit.pow.two]
 bit_floor(): x == 0, 0; otherwise the maximal value y such that has_single_bit(y) is true and y <= x [bit.pow.two]
 bit_width: x == 0, 0; otherwise one plus the base-2 logarithm of x, with any fractional part discarded [bit.pow.two]
