This change removes mcentral.nmalloc and adds mcache.local_nsmallalloc which fulfills the same role but may be accessed non-atomically. It also moves responsibility for updating heap_live and local_nsmallalloc into mcache functions. As a result of this change, mcache is now the sole source-of-truth for malloc stats. It is also solely responsible for updating heap_live and performing the various operations required as a result of updating heap_live. The overall improvement here is in code organization: previously malloc stats were fairly scattered, and now they have one single home, and nearly all the required manipulations exist in a single file.
