get rid of the hack that used to be in IRGenDebugInfo.
This commit also adds a bunch of interesting testcases for function args.
Fixes <rdar://problem/15464454> Arguments sometimes go missing.

This completes the FileUnit refactoring. A module consists of multiple
FileUnits, which provide decls from various file-like sources. I say
"file-like" because the Builtin module is implemented with a single
BuiltinUnit, and imported Clang modules are just a single FileUnit source
within a module.
Most modules, therefore, contain a single file unit; only the main module
will contain multiple source files (and eventually partial AST files).
The term "translation unit" has been scrubbed from the project. To refer
to the context of declarations outside of any other declarations, use
"top-level" or "module scope". To refer to a .swift file or its DeclContext,
use "source file". To refer to a single unit of compilation, use "module",
since the model is that an entire module will be compiled with a single
driver call. (It will still be possible to compile a single source file
through the direct-to-frontend interface, but only in the context of the
whole module.)

Now that everything is done in terms of FileUnits, we don't need LoadedModule
anymore, and now that FileUnits just use virtual dispatch, we don't need to
indirect through ModuleLoader to distinguish them.
This doesn't quite simplify as much as it could, because the next change is
going to combine TranslationUnit and Module.

Part of the FileUnit restructuring. A serialized module is now represented as
a TranslationUnit containing a single SerializedASTFile.
As part of this change, the FileUnit interface has been made virtual, rather
than switching on the Kind in every accessor. We think the operations
performed on files are sufficiently high-level that this shouldn't affect us.
A nice side effect of all this is that we now properly model the visibility
of modules imported into source files. Previously, we would always consider
the top-level imports of all files within a target, whether re-exported or
not.
We may still end up wanting to distinguish properties of a complete Swift
module file from a partial AST file, but we can do that within
SerializedModuleLoader.

decl context of the type alias.
This implements <rdar://problem/15290346> "typealias sugar needs to be
mangled into debug info mangled type names".

Instead of hardcoding Builtin.Word to be an alias for Builtin.Int64, make it its own type of abstract pointer width.
- Change BuiltinIntegerType's width representation to accommodate abstract widths.
- In the AST and in SIL, store values of the types as the greatest supported size for the abstract width (64 bits for a pointer).
- Add some type safety to the ([sz]ext|trunc)(OrBitCast)? builtins that they're used appropriately given the upper and lower bounds of the abstract sizes they're working with.
- Now that Builtin.Word is a distinct type, give it its own mangling.
- In IRGen, lower pointer-sized BuiltinIntegerType appropriately for the target, and truncate lowered SIL values if necessary.

back to the beginning of the function.
Add a large number of testcases that check the sanity of the return
locations in various scenarios involving implicit/explicit returns,
cleanups, and multiple return locations per function.
