Unroll PUT_BITS() loop and improve compile-time visibility.
Unroll PUT_BITS() loop and improve compile-time visibility.

We *know* that we'll go round the loop at least once if (nr) >= 8, and
we *might* go round it one more time. There's no need for a loop.

This gives around 8% performance improvement.
