In general, this forces SILGen and IRGen code that's grabbing
a declaration to state whether it's doing so to define it.
Change SIL serialization to serialize the linkage of functions
and global variables, which means also serializing declarations.
Change the deserializer to use this stored linkage, even when
only deserializing a declaration, and to call a callback to
inform the client that it has deserialized a new entity.
Take advantage of that callback in the linking pass to alter
the deserialized linkage as appropriate for the fact that we
imported the declaration. This computation should really take
advantage of the relationship between modules, but currently
it does not.

Dynamic forms of these methods will ultimately move to the fully general TypeInfo class, but for now I'm focusing on getting fixed-layout unions working. Set up methods on FixedTypeInfo for getting the fixed count of extra inhabitants and the spare bit mask for a type. Have the default implementation of extra inhabitants count use the spare bits. For now, only actually set spare bits for types with IR-level single scalar non-power-of-two integer representation (e.g., i1, or i21).

the new LoadableTypeInfo refinement interface.
This protects against bugs which would introduce unbalanced
allocations of temporary memory.

This cleans up some wishy-washy control flow that relied on the uncurryLevel of a type to distinguish ObjC methods from freestanding C functions. While we're here, clean up all the places we use ad-hoc comparison logic on the AbstractCC enum to use switches that properly cover the enum.

Sever the last load-bearing link between SILFunction and SILConstant by naming SILFunctions with their mangled symbol names. Move the core of the mangler up to SIL, and teach SILGen how to use it to mangle a SILConstant.

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.

and non-deallocating destructors and allocating/non-allocating
constructors.
Non-deallocating destructors might not play well with ObjC
classes; we might have to limit them to pure-swift hierarchies.
No functionality change except that I decided to not force
destructors to have internal linkage unconditionally.

protocol witnesses over to the new API. There's some badness
that we're papering over here involving generic types, but
this is a necessary first step.

an owner attached. Use this to implement [byref(heap)]. Force
locals to the heap if they've been referenced in a way that requires
this.

require Explosion.h. This is just to isolate the parts
of IR-generation that shouldn't have anything to do with
emitting code within functions.
