- Added a couple of new targets: - libswiftDriver, which contains most of the driver implementation - swift_driver, which produces the actual executable - Added centralized version information into libswiftBasic. - Added a new "Driver Design & Internals" document, which currently describes the high-level design of the Swift driver. - Implemented an early version of the functionality of the driver, including versions of the Parse, Pipeline, Bind, Translate, and Execute driver stages. Parse, Pipeline, and Bind are largely implemented; Translate and Execute are early placeholders. (Translate produces "swift_driver --version" and "ld -v" commands, while Execute performs all subtasks sequentially, rather than in parallel.) This is just the starting point for the Swift driver. Tests for the existing behavior are forthcoming. Swift SVN r10933
