1b3a5ccb6e Prefetch the backreference hashtable bucket. 
Place the prefetch before the last distance checks, to give the prefetch enough time to work.

c1c76e993f Don't check cur_ix_masked against ring_buffer_mask. 
`cur_ix_masked` isn't changing from iteration to iteration, and `max_length` ensures we never find a match long enough to walk off the ring buffer.

9351fa7ffb Compare 4 bytes when checking if a longer match is possible. 
Loading and comparing 4 bytes is ~as fast as 1 byte, but allows us to avoid more full match length calculation.

3ebb2d30ab Move serialized dictionary feature behind the flag. 
BROTLI_SHARED_DICTIONARY_SERIALIZED enum value is a part of API,
but it should not be used (will cause failures).
Changing how serialized dictionaries work won't be considered as an API change, until this feature is enabled.
Enabling this feature in the future will be considered as a "compatible" change.
