79f1ee2fc0 Move junking out of arena/tcache code. 
This is debug only and we keep it off the fast path.  Moving it here simplifies
the internal logic.

This never tries to junk on regions that were shrunk via xallocx.  I think this
is fine for two reasons:
- The shrunk-with-xallocx case is rare.
- We don't always do that anyway before this diff (it depends on the opt
  settings and extent hooks in effect).

6c3491ad31 Tcache: Unify bin flush logic. 
The small and large pathways share most of their logic, even if some of the
individual operations are different.  We pull out the common logic into a
force-inlined function, and then specialize twice, once for each value of
"small".

We wrote `return some_void_func()` in a function returning void, which is
confusing and triggers warnings on MSVC.

1d449bd9a6 Emap: Internal rtree context setting. 
The only time sharing an rtree context saves across extent operations isn't a
no-op is when tsd is unavailable.  But this happens only in situations like
thread death or initialization, and we don't care about shaving off every
possible cycle in such scenarios.

ba0e35411c Rework the bin locking around tcache refill / flush. 
Previously, tcache fill/flush (as well as small alloc/dalloc on the arena) may
potentially drop the bin lock for slab_alloc and slab_dalloc.  This commit
refactors the logic so that the slab calls happen in the same function / level
as the bin lock / unlock.  The main purpose is to be able to use flat combining
without having to keep track of stack state.

In the meantime, this change reduces the locking, especially for slab_dalloc
calls, where nothing happens after the call.

ca1f082251 Disallow merge across mmap regions to preserve SN / first-fit. 
Check the is_head state before merging two extents.  Disallow the merge if it's
crossing two separate mmap regions.  This enforces first-fit (by not losing the
SN) at a very small cost.
