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.

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

Introduce a new swift_dynamicCast pair that take in a general metatype
pointer, rather than the more specific class-metatype pointer used for
class downcasts, and grab the class out of that general metatype
pointer, which may actually be an Objective-C wrapper. This is
slightly slower, but it works for the super-to-archetype cases like
T(an_NSObject), where T can have either kind of metadata.
NSTypedArray<T> is actually run-time type checked now, yay!

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.

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.

This is kindof a pain in a few places where the type system
doesn't propagate canonicality. Also, member initializations
are always direct-initializations and so are allowed to use
explicit constructors, which is a hole in our canonicality
tracking. But overall I like the idea of always working
with canonical types.

by abstraction from the concrete return type.
This basically gets generic calls working totally as long
as there's no remapping required.
