The new library, swiftEmbeddedPlatformPOSIX, implements all of the _swift_XYZ functions needed to support Embedded Swift as shims on top of a POSIX system that provides posix_memalign, free, putchar, and so on. This offers an easier way to bridge between the prior ad hoc requirements of Embedded Swift and the newer platform abstraction layer. Part of rdar://164057124
