Break up headers into constituent parts This is part of a broader change to make header files better represent the dependencies between one another (see https://github.com/jemalloc/jemalloc/issues/533). It breaks up component headers into smaller parts that can be made to have a simpler dependency graph. For the autogenerated headers (smoothstep.h and size_classes.h), no splitting was necessary, so I didn't add support to emit multiple headers.

Pull out caching for a bin into its own file. This is the first step towards breaking up the tcache and arena (since they interact primarily at the bin level). It should also make a future arena caching implementation more straightforward.

struct tcache_s {
Optimizing TSD and thread cache layout. 1) Re-organize TSD so that frequently accessed fields are closer to the beginning and more compact. Assuming 64-bit, the first 2.5 cachelines now contains everything needed on tcache fast path, expect the tcache struct itself. 2) Re-organize tcache and tbins. Take lg_fill_div out of tbin, and reduce tbin to 24 bytes (down from 32). Split tbins into tbins_small and tbins_large, and place tbins_small close to the beginning.

* The pointer stacks associated with bins follow as a contiguous array.
* During tcache initialization, the avail pointer in each element of
* tbins is initialized to point to the proper offset within this array.
