This is groundwork for setting [DY]LD_LIBRARY_PATH ahead of time when
invoking the interpreter, which is rdar://problem/23588774. The next
commit will set up the appropriate variable and use -driver-print-jobs
to test it; the following commit will apply the environment variable
when running a job.
This was just a wrapper around SmallVector that optionally owned the Job pointers
in it. Now that all Jobs are owned by the Compilation, we don't have to worry
about this any more.
No functionality change.

Together with -wmo it enables multi-threaded compilation.
I didn't want to reuse the -j option for this, because -num-threads (even if n == 1) does change the generated code.
For details see commit message of r25930.

...and rename Command to Job (previously the name of the base class).
We never generated job lists directly contained in other job lists, so
let's not even worry about this case. We may some day need to break Job
out into separate subclasses (Clang has Command and FallbackCommand in
addition to JobList), but we should be able to keep the list separate.
No intended functionality change.

This will allow the driver to specify the location for, among other things, the partial swiftmodule generated by a single frontend invocation.

- 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.
