TCMalloc doesn't give detailed statistics on the state of the freelist, which makes it difficult to analyze severe memory fragmentations like those in SERVER-22906 or SERVER-20306.
Improve the TCMalloc serverStatus() output by traversing the freelists for the different size classes, giving us more information. Add a new function in TCMalloc that exposes these statistics efficiently, allowing us to create a BSON object out of them rather than returning a text blob that cannot be parsed.
