Shifts all the bits in the array to the left by the given number of
bits. The leftmost bits are dropped, and 0's are appended to the end
to fill up the vacant bits.
Warning: unused bits in the final word up to the next word
boundary may be overwritten by this operation. It does not attempt to
preserve bits past the end of the array.
