This just adds another possible output kind and forwards it to the frontend.
Note that in builds without an output map, this will just dump the dependencies
next to the output file, which is a temp file whose name is chosen randomly.
That's not so useful, but we can fix it later.

This currently handles owned -> guaranteed argument conversion and dead argument
elimination.
RecursiveOwnedParameter||90.0%
ClassArrayGetter|||||||||23.3%
Life|||||||||||||||||||||16.7%
Prims||||||||||||||||||||11.2%
StringWalk|||||||||||||||5.7%
The next step is to implement SROA and address -> value optimizations.

This tracks top-level qualified and unqualified lookups in the primary
source file, meaning we see all top-level names used in the file. This
is part of the intra-module dependency tracking work that can enable
incremental rebuilds.
This doesn't quite cover all of a file's dependencies. In particular, it
misses cases involving extensions defined in terms of typealiases, and
it doesn't yet track operator lookups. The whole scheme is also very
dependent on being used to track file-level dependencies; if C is a subclass
of B and B is a subclass of A, C doesn't appear to depend on A. It only
works because changing A will mark B as dirty.

Whenever we add a requirement, we now know
(1) Why we added the requirement, e.g., whether it was explicitly written, inferred from a signature, or introduced by an outer scope.
(2) Where in the source code that requirement originated.
Also add a debugging flag for dumping the archetype builder information, so we can write tests against it.
This is effectively NFC, but it's infrastructure to help a number of requirements-related tasks.

Previously we hardcoded a few important default CPUs, ABIs, and features into
Swift's driver, duplicating work in Clang. Now that we're using Clang's
driver to create the Clang "sub-compiler", we can delegate this work to Clang.
As part of this, I've dropped the options for -target-abi (which was a
frontend-only option anyway) and -target-feature (which was a hidden driver
option and is a frontend-only option in /Clang/). We can revisit this later
if it becomes interesting. I left in -target-cpu, which is now mapped
directly to Clang's -mcpu=.

This patch adds the ability (-enable-experimental-unavailable-as-optional) to
treat potentially unavailable declarations as if they had optional types. For
the moment, this is only implemented for global variables.
The high-level approach is to (1) record the potential unavailability of a
declaration reference in the overload choice during constraint generation; (2)
treat the declaration as if it had an optional type during overload resolution
(this is similar to how optional protocol members are treated); and (3) add an
implicit conversion (UnavailableToOptionalExpr) during constraint application
to represent the run-time availability check and optional injection.
This patch does not implement SILGen for UnavailableToOptionalExpr.

for testing purposes.
When enabled, if the typechecker tries to typecheck a decl or unresolved identifier with the provided
prefix, then an llvm fatal_error will get triggered.
This approach has the advantage that it is very easy to write tests for unnecessary typechecking for a wide range of functionality,
for the compiler or SourceKit, for code-completion, indexing, etc.

In this mode, use nullability information on the result type of the
initializer or factory method to determine failability of the
initializer. This is behind the flag
-enable-objc-failable-initializers until we have the SILGen support in
place.

Revert "For debugging purposes allow passes to stop any more passes from running by calling PassManager::stopRunning()."
This reverts commit r20604.
This reverts commit r20606.
This was some debugging code that snuck in.

This allows swiftFrontend to drop its dependency on swiftDriver, and could
someday allow us to move the integrated frontend's option parsing out of
swiftFrontend (which would allow other tools which use swiftFrontend to
exclude the option table entirely).
