1930222f3b Runtime: Instruments support plan B 
Rather than go through reentrant and problematic contortions to make Swift
work with the existing Instruments hooks, they agreed to just patch some
globals that we provide to get their logic to be activated.

3e4f388b1f Runtime: allow realloc 
Nothing should call this. We'll eventually log a warning. For now, this
silences a build warning.

2e76e91466 Runtime: corner case heap policy tweak 
Only the compiler calls this API and the compiler never needs
placeholder heap allocations.

09f2e9ed57 WIP Runtime: Zone cleanup to use C++ more. NFC. 
All of the malloc zone APIs are clumsy object-oriented design in C, but that
does not mean we should be too. This should clarify the design more too.

9816e2ab05 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
