This functionality doesn’t really change what we accept right now, because we eagerly import all of the methods of a class when we do *any* kind of lookup into the class. However, when we manage to stop doing that, this operation will become more important.

This performs very conservative dependency generation for each compile task
within a full compilation. Any source file, swiftmodule, or Objective-C
header file that is /touched/ gets added to the dependencies list, which
is written out on a per-input basis at the end of compilation.
This does /not/ handle dependencies for the aggregated swiftmodule, swiftdoc,
generated header, or linked binary. This is just the minimum needed to get
Xcode to recognize what needs to be rebuilt when a header or Swift source
file changes. We can revisit this later.
This finishes <rdar://problem/14899639> for now.

Also, create the Clang module loader directly rather than indirecting through
a "get constructor" function. It's no longer a valid configuration to not
have a Clang importer.

...unless the functions are declared [transparent], or if we're in an
immediate mode (in which case we won't get a separate chance to link
against the imported TUs).
This is an optimization that will matter more when we start dealing with
Xcode projects with many cross-file dependencies, especially if we have
some kind of implicit import of the other source files in the project.
In the future, we may want to parse more function bodies for the purpose
of inlining, not just the transparent ones, but we weren't taking
advantage of that now, so it's not a regression. (We're still not taking
advantage of it even for [transparent] functions.)

Now that we have true serialized modules, the standard library can import
the Builtin module without any special direction (beyond -parse-stdlib),
and anyone can include those modules without special direction.
Swift SVN r6752
This causes the SourceLoader to recursively parse the imported module in standard
library mode, giving it access to the Builtin module.
This is all a terrible hack and should be ripped out with great victory someday, but
until we have binary modules that persist the build setting used to produce the
module, this is the best we can do.

This replaces the obscure, inefficient lookup into extensions with
something more straightforward: walk all of the known extensions
(available as a simple list), then eliminate any declarations that
have been shadowed by other declarations. The shadowing rules still
need to consider the module re-export DAG, but we'll leave that for
later.
As part of this, keep track of the last time we loaded extensions for
a given nominal type. If the list of extensions is out-of-date with
respect to the global generation count (which tracks resolved module
imports), ask the modules to load any additional extensions. Only the
Clang module importer can currently load extensions in this manner.
Swift SVN r5223
This paves the way for having a Swift module importer. The eventual goal
here is to eliminate all explicit uses of the Clang module loader, but
I'm not going to push too hard on that for now.
