...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.)

We haven't fully updated references to union cases, and enums still are not
their own thing yet, but "oneof" is gone. Long live "union"!
Swift SVN r6783
This should include all of the attributes we care about for the time being.
Only the resilience attributes (not designed) and [force_inline] are left
unaccounted for.

Previously, cross-references used a simple access path to refer to values
in other modules, but extensions have no name. They also accidentally
picked up values in extensions anyway, because lookupDirect includes
members in extensions. Now, we filter out values that don't come from
the referenced module, which may not be the same module the base type
comes from.
Swift SVN r6301
Classes are exactly like structs except that they may have a base class.
However, this type will show up in the inheritance list. That means we
don't actually need to serialize it twice; we can just grab the base class
from the inheritance list.
Swift SVN r6133
...in a quest for completeness. ArrayTypes don't actually work yet
(single-dimensional arrays are typed as slices), but when they do the test
that is currently XFAIL'd should start passing.
With this, all non-transient types can now be serialized and deserialized.
Swift SVN r6101
Instead, special-case cross-references to use the empty identifier as the
name of the Builtin module. This way imported modules will be able to use
builtin types and functions without the main TU having access.
Swift SVN r5947
When loading a module, we now try to load its dependencies as well.
If one of those dependencies can't be loaded, we emit an error message.
Swift SVN r5796
Like everything else, there are several caveats: no generic params, no
attributes, and (for now) no arguments. Pattern support is coming next.
Swift SVN r5701
Unlike Clang, Swift's DeclContexts are not all Decls. However, I believe
each DeclContext that is /serialized/ will be either a decl, a
TranslationUnit, or a FuncExpr for a function with an actual declaration.
This might turn out to be wrong if (a) SIL needs proper DeclContexts for
variables in function bodies, or (b) we need to serialize anonymous
closure default arguments.
Along with an extension of the ConstructorDecl placeholder code, this allows
us to round-trip empty structs.
Swift SVN r5532
...but don't do anything with them yet. This does check that they're being
correctly serialized, though.
This introduces a new ADT, PointerIntUnion, which like PointerUnion is an
efficient variant type using the lowest bit of data as a discriminator.
By default, the union can store any pointer-bits-minus-one-sized integer,
but both the integer type and the underlying storage type can be
customized.
Swift SVN r5321
We can bikeshed on this later, but for now we can use a very explicit
extension that has no chance of stepping on any existing extension.
