b94e9e3f76 [driver] Slightly refactored Driver’s handling of OutputMode.
Instead of having buildActions() call the private Driver::getOutputMode() function, establish an OutputMode using a new Driver::buildOutputMode() function.
This change will allow the OutputMode to be more easily shared across functions without needing to generate it each time (though, at the moment, only buildActions() uses the OutputMode).

e9599f249d [driver] Added support for adding a MergeModuleJobAction to the Action graph.
Updated Driver::OutputMode to also contain a ShouldGenerateModule field.
Updated Driver::getOutputMode() to set OutputMode::ShouldGenerateModule appropriately.
Updated Driver::buildActions() to insert a MergeModuleJobAction into the Action graph if the Driver’s OutputMode indicates that a module should be generated.

40b38c40b2 [driver] Reworked Driver::buildJobsForAction() so that it doesn’t create the same Job multiple times.
Since a Job may be reached through multiple paths in the dependency graph, we
need to include support for caching Jobs. (Currently, the cache maps
Action/ToolChain pairs to Jobs.)

As a result of these changes, Tool::constructJob() and
Driver::buildJobsForAction() return a plain Job *, instead of a
std::unique_ptr<Job>, since the Jobs returned by buildJobsForAction() no longer
need to be unique.

3d9f94e715 Properly implemented "swift_driver -driver-print-bindings".
This produces output similar to "clang -ccc-print-bindings".
Also added several tests to ensure that "swift_driver -driver-print-bindings"
behaves as expected.

ed2038585f Initial set of changes to add a new 'swift_driver' executable.
- 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.
