Change subject: mem-cache: Add compression stats
......................................................................
mem-cache: Add compression stats
Add compression statistics to the compressors. It tracks
the number of blocks that can fit into a certain power
of two size, and the number of decompressions.
For example, if a block is compressed to 100 bits, it will
belong to the 128-bits compression size. Although it could
also fit bigger sizes, they are not taken into account for
the stats (i.e., the 100-bit compression will fit only the
128-bits size, not 256 or higher).
We save stats for compressions that fail (i.e., compressed
size is bigger than original cache line size).
