Hi, there are some optimizations possible to make. The most important one would
be to avoid the load from _gst_bit_writer_bit_filling_mask[], thus removing
that static data. From what I understand,
_gst_bit_writer_bit_filling_mask[nbits] reduces to (0xff >> (8 - nbits)). i.e.
I'd prefer a computation instead of a load from memory, even if it is cached.

Last but not least, prior to performing optimizations, proper unit testing are
required. Thanks.
