...when interpreting. Otherwise, the script may depend on library X, which
depends on library Y, where library Y is a standard Swift library, located
in lib/swift/$PLATFORM/.

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.

This makes it easier to make interpreter modes behave differently from
compilation modes. Obviously that's a trade-off, since the two modes also
share plenty, but given how few of the existing CompileJobAction checks had
to be modified for the new InterpretJobAction, I think this is the right
way to go.
Groundwork for setting [DY]LD_LIBRARY_PATH ahead of time when invoking the
interpreter, which is rdar://problem/23588774.
This reverts commit 58cfa27eb5.
We require at least clang-3.6 for C++14 build support but
Ubuntu 14.04's clang-3.6 package does not lay down the symlink
/usr/bin/clang++ -> /usr/bin/clang++-3.6. We will require a
clang++ alternatives entry or symlink when building for these
systems (see README.md).
In most Linux distributions, installing a clang package other than the
default unversioned one will not install a symlink from /usr/bin/clang++
-> /usr/bin/clang++-N-M, which can break builds with a not so great
diagnostic (a separate problem).
"ld" and "clang++" are hard-coded in the link job actions, so provide a
frontend flag, -linker-path, as a customization point for these.

Deploying to older OSs requires linking in a compatibility library called
"arclite", but this library isn't open source and won't be distributed with
our open source downloads. Fall back to the version in Xcode.
The next step is to remove the local symlink used in builds, but I wanted to
handle that separately.

inside a swift ast section in an object file so it can be passed to the
linker. The driver automatically wraps merged swiftmodules iff the target
is ELF.

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.
