the metadata objects for classes. This is currently only
done for methods defined in the main class body, and it's
(naturally) totally fragile, and it's screwed up in a
couple known ways w.r.t. generic classes: there's no
thunking when the overrider differs by abstraction from
the overridden method, and methods on classes currently
expect to get all the type arguments passed directly
and thus will disagree in signature from members of
non-generic classes. Also, of course, we're not using
any of this in the call infrastructure. But it's progress.

of protocol types to correctly handle self-assignment.
This ends up creating such a large amount of code that it's
worth extracting into its own helper function. Fortunately,
this can be the same helper function for every protocol type.

first, we weren't registering the cleanup for the temporary
if it needed materialization, and second, we were potentially
double-consuming cleanups associated with the l-value, e.g.
subscript indices.

heap allocations it makes, and switch swift_alloc over to pass
that pointer in as well as the alignment. Also, compute
whether a type is POD during its generation and cache that in
the object, and introduce a method on TypeInfo to destroy an
object in memory.
