Doug Gregor ae1e3d0865 Build a static library that implements the Embedded Swift platform layer on POSIX
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.
