[BZip2] Use better versions of bit writer functions
...
First, write(unsignedNumber:) is better than write(number:) when the argument is already UInt, since it does one fewer precondition check and does not do additional integer conversion. Secondly, using write(number:) to write one bit was very inefficient.

[BZip2] Slightly optimize MTF transform of selectors during compression
...
It can be statically proven that the output of MTF transform lies within a certain range, so a guard check can be replaced with an assertion.
