That's DYLD_LIBRARY_PATH on OS X and LD_LIBRARY_PATH on Linux for -L,
and DYLD_FRAMEWORK_PATH on OS X for -F.
Note that this commit doesn't actually include the setenv calls yet, so an
end-to-end test is coming in the next commit.
Part of rdar://problem/23588774
The "Tool" abstraction wasn't buying us enough to deserve the added
complexity. Now a ToolChain turns Actions into Jobs, and every helper
tool is searched for relative to Swift first. Much simpler.

- 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.
