When nbits is a multiple of the word size, the pack_entropy function
right shifts the mask by the type width, which is undefined. In
practice, the 64-bit shift compiles to a no-op and the implementation
depends on this behaviour, so this patch changes the function to skip
the masking if nbits is multiple of the word size.
