1f5b775bc7 Use metatype pointers as generic type arguments. Movements
towards optimizing generic calls to derive things from the
'this' pointer, which is actually crucial for virtual
dispatch (to get all methods to agree about how the
implicit arguments are passed).  Fix a number of assorted
bugs in metadata emission.  Lots of assorted enhancements.

This was proving surprisingly difficult to actually tease
apart into smaller patches.

179e260ea3 Add an abstraction to encapsulate a Decl + explosion level +
uncurrying level, which is something I find myself passing around
quite a bit.  Make sure that it can propagate getter/setter
references in the same way.

3467e63516 Emit pointers to final overriders of member functions into
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.

2d03d842f5 Move class metadata emission into GenMeta.cpp. The main
motivation for this is to re-use code involving generic nominal
types.

72ebeee76f Try to optimize assignment a bit more, and fix assignment
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.

b3b71178a5 Fix a pair of bugs with partial updates of logical l-values:
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.

bc32a8aedb Fix a bug with returning value that need to be refcounted:
we want to do a take-load out of the return address slot
instead of a normal load, or else we'll end up +1'ing an
already +1 value.

f3e27d90ff Change IR-generation so that it emits metadata objects for the
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.
