When running in immediate mode, generate a global initializer when an extension is defined for an ObjC class that uses the class_replaceMethod runtime function to dynamically add the extension methods to the ObjC class.
Swift SVN r4153
Emit ObjC stubs and categories for methods defined in extensions of ObjC-compatible classes. This makes extensions of ObjC classes available to ObjC in statically compiled code. For immediate-mode code we'll still need to dynamically register extension methods using the ObjC runtime.

For Objective-C super calls, build an objc_super struct value containing the receiver and class/metaclass object and pass it to objc_msgSendSuper2. For Swift super calls, emit a direct call to the super implementation.
Swift SVN r4023
Fix up the thunk generator so it knows how to turn byval C arguments back into Swift explosions, so that methods that take NSRects as arguments or give NSRect as their return value can be exported as objc methods.
Swift SVN r4010
Push LLVM attribute generation from expandAbstractCC into getFunctionSignature and CallEmission so that they can generate sret and/or byval attributes per-argument according to the calling convention. Copy our bogus rule for emitting sret returns (more than three elements in the explosion) and reuse it to pass large struct values as byvals rather than as explosions. This should be good enough to get both 'NSRect' and
'NSRange', 'NSSize' etc. to pass correctly to ObjC methods. Next step is to set the AbstractCC correctly for imported func decls so that standalone C functions follow the same bogus rule.

Notably, there is still no support for +1 return values,
so we'll leak when doing alloc/init and so on; but this gets
the fundamentals in place. A lot of the extra stuff in here
is dealing with mapping between metatypes and class objects.

When generating IR for the JIT, use sel_registerName() to unique the
selector references we generate. Static code doesn't need this
pessimization. Fixes <rdar://problem/12764732>.
Swift SVN r3403
First, keep track of each of the selectors we emit and dump them into the
llvm.used global so that they don't get thrown away by the
optimizer. Second, emit Objective-C module-level named metadata so
that the linker knows it needs to unique selectors. Otherwise,
uniquing doesn't happen when Swift code is compiled into a separate
dylib.
Swift SVN r3287
wrap it in an 'id' type in the standard library.
Also fix a bug noticed by inspection where initWithTake for
function types wasn't entering a cleanup for the taken value.
This probably doesn't matter for existing possibilities, but
it's potentially important under exceptions.
