The driver infers the filename from the module file by replacing the extension,
and passes the explicit path to the swiftdoc file to the frontend. But there
is no option in the driver to control emission of swiftdoc (it is always
emitted, and name is always inferred from the swiftmodule name).
The swiftdoc file consists of a single table that maps USRs to {brief comment,
raw comment}. In order to look up a comment for decl we generate the USR
first. We hope that the performance hit will not be that bad, because most
declarations come from Clang. The advantage of this design is that the
swiftdoc file is not locked to the swiftmodule file, and can be updated,
replaced, and even localized.

The standard library likes to have default definitions for associated types,
which is good. Often the /choice/ of default type, however, is a type that
(indirectly) conforms to the very protocol containing the associated type.
Rather than try to make sure everything is present all at once, just delay
the deserialization of the default definition until it's actually requested.
This does swell the size of AssociatedTypeDecl by two words. I've filed
<rdar://problem/16266669> to remind myself to try to reduce this.

Make the name lookup interfaces all take DeclNames instead of identifiers, and update the lookup caches of the various file units to index their members by both compound name and simple name. Serialized modules are keyed by identifiers, so as a transitional hack, do simple name lookup then filter the results by compound name.

to the archetypes of their generic parameter declarations.
This was a major inconsistency that was causing a lot of
problems with deserialized generic functions in the presence
of chained module files. In particular, what would happen is
that all the deserialized uses of the archetype would be
mapped to a freshly-created archetype, but the GenericParamList
would refer to GenericTypeParamDecls deserialized from
(potentially) a different ModuleFile and therefore using a
different archetype (since the deserializer assumes that
different modules never share archetypes).
The fix relies on processing a generic parameter list before
any references to the archetypes. Unfortunately, we have
bogus references to archetypes in substitution lists scattered
everywhere in SIL and the AST. I've introduced a really
gross hack where we allow archetypes to be created in that
way but just drop them (in favor of the parameter's archetype)
after processing the generic parameter list; this should
work as long as all the decontextualized references are
basically pointless, but like I said, it's gross, and I've
filed rdar://16240384 to clean it up.

With this commit, we can deserialize the stdlib. Still running into
issues related to linking that requires a consultation with John. That
will come in a later commit.

Swift can now find modules inside framework bundles matching this layout:
Foo.framework/
Foo.swiftmodule/
ARCH.swiftmodule
Currently, ARCH is the architecture name used by build configurations (#if),
but this was more done out of convenience than anything else (there's
currently no access to the current target from the ASTContext). We'll need
to revisit this if/when we decide to support architecture subtypes (armv7s
vs. armv7 vs. arm), at which point we'll also have to deal with fallback
architectures.
Framework search paths are specified using -F. Like bare import paths, there
are currently no "built-in framework search paths".
The master plan for Swift frameworks is in <rdar://problem/16062602>.
