Runtime: the Swift heap/zone
...
Good:
* We now no longer wrap the system malloc zone.
* Tiny allocation quantum is pointer sized, not 16 bytes.
* Far less metadata overhead than the system malloc zone.
Bad:
* Our heap density isn't quite as good as the default zone. This is a O(1)
versus O(N) tradeoff. The default malloc zone has been trending in this
direction too.
TODO:
* Introspection
* Tune secondary fast paths
* Huge allocations

This reverts r14453, which seems to be breaking the build.

runtime: always provide swift_retainAndReturnThree()

We've disabled the fast entry points for now on the simulator, but the
ARC optimizer doesn't know that. This is a workaround.
