Rename bridging "convert" functions to start with '_'.
...
This is part of our poor-man's internal compiler SPI hiding
in the standard library. We don't want these functions showing
up in code completion, etc.

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

Revert "Runtime: hardcode less about the OS implementation"

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

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