Start sketching out a way for individual jobs to request filelists for
their inputs or their outputs. This should cover all the cases mentioned
in ad945426.
More https://bugs.swift.org/browse/SR-280.
Previously jobs had to grovel this information out of the raw argument
list, which dropped the types we had inferred on input files. This
makes things more consistent across the compiler, though arguably we
should be able to designate "primary" and "non-primary" inputs on a
per-action basis rather than resorting to "global" state.
Use this new information to stop passing object file inputs to the
Swift frontend, fixing rdar://problem/23213785.
The list wouldn't have to live on the Compilation, but I'm going to use
it to fix SR-280 / rdar://problem/23878192 as well.
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.

This only works when swift is packaged with Xcode or installed as a command
line tool, but those are the important cases.
<rdar://problem/14395800>, again.

This emits a dynamic library as the final build product (rather than an
executable), as well as implicitly passing -parse-as-library to the frontend.
Swift SVN r12930
- 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.
