Refactor per-run bitmap manipulation functions so that bitmap offsets only
have to be calculated once per allocator operation.

Make nil const.

Update various comments.

Remove/avoid division where possible.

For the one division operation that remains in the critical path, add a
switch statement that has a case for each small size class, and do division
with a constant divisor in each case.  This allows the compiler to generate
optimized code that does not use hardware division [1].
