ARROW-1928: [C++] Add BitmapReader/BitmapWriter benchmarks

Also improve the BitmapWriter implementation (around 18% faster here - on Ubuntu 16.04 with gcc 4.9).

I experimented with a different implementation for BitmapReader (storing the bit mask instead of the bit offset), but it came out surprisingly slower.

Closes #1915 from pitrou/ARROW-1928-bitmap-benchmarks and squashes the following commits:
