handling non-fixed layouts.
This uncovered a bug where we weren't rounding up the header
size to the element alignment when allocating an array of archetypes.
Writing up a detailed test case for *that* revealed that we were
never initializing the length field of heap arrays. Fixing that
caused a bunch of tests to crash trying to release stuff. So...
I've left this in a workaround state right now because I have to
catch a plane.

seems that this is not a good idea, because it seems statically live from the SIL
SuperToArchetypeInst. However, apparently nothing in the testsuite exercises
this code, so I'll need to discuss and a testcase to know how much logic needs
to be ressurrected from SVN. rdar://13681541

ObjC classes don't have a deallocating destructor, so we can't call up to it in a class derived from an ObjC class. Hack SILGen not to emit a call to the superclass destructor of a class inherited from an ObjC class. This is the wrong thing, but it looks like destructors don't get hooked up to ObjC dealloc methods anyway yet, so what the Swift destructor of an ObjC-derived class does is moot right now. This lets us remove the guards from IRGen that prevented ObjC destructors from being emitted.

Teach SILGen how to emit the implicit elementwise constructor for structs and the implicit default constructor for classes, and eliminate the now dead IRGen code for them. Add a StructInst SIL instruction to represent constructing a loadable struct value from elements, analogous to TupleInst for tuples.

and supporting logic.
PathComponent and LValue are (apparently unnecessarily) kept alive by

redefinition (or linkage type) bug that causes two tests to fail. I filed
rdar://13670581 to track this and am plowing forward, since they seem minor.

The argument to archetype_method can be a metatype, so allow that. While we're here, implement lowering for AssociatedMetatypeInst, and fix initial bringup of SIL-IRGen so that polymorphic arguments get emitted into the entry point BB instead of a random other BB.

When lowering SIL builtin ConstantRefs, just stash away the FuncDecl, and pass that decl on to a tweaked version of emitBuiltinCall when the constant is applied.
