Adds a -working-directory option which can be used to modify how
relative paths are resolved. It affects all other paths used in driver
options (controlled by a new ArgumentIsPath flag on options) as well as
the contents of output file maps and auxilliary file paths generated
implicitly by the compiler itself.

Replace `NameOfType foo = dyn_cast<NameOfType>(bar)` with DRY version `auto foo = dyn_cast<NameOfType>(bar)`.
The DRY auto version is by far the dominant form already used in the repo, so this PR merely brings the exceptional cases (redundant repetition form) in line with the dominant form (auto form).
See the [C++ Core Guidelines](https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#es11-use-auto-to-avoid-redundant-repetition-of-type-names) for a general discussion on why to use `auto` to avoid redundant repetition of type names.
This will make future testing easier: Xcode can add a new type to the map
to support newer compilers without breaking older compilers.

Add -whole-module-optimization option as synonym of
-force-single-frontend-invocation (for now). Add support for
-output-file-map when using -whole-module-optimization with multiple
input files -- the key for the single output file's map is the empty string.

LLVM's system_error.h has been changed to forward to the standard
version of the same. Update usage for the minor API changes that this
entails.
Based in part on a patch by Justin Bogner.
Swift SVN r18832
OutputFileMap is responsible for loading an "output file map", which maps input
paths (as specified on the command line) to per-output-kind paths.
This will permit the explicit specification of the outputs of each frontend
invocation: the primary output (e.g. "object" or "sil"), as well as the partial
swiftmodule and serialized diagnostics outputs (if requested).
The format (in JSON) is:
{
<input> = {
<kind> = <path>,
<kind> = <path>,
...
},
<input> = { ... },
...
}
