We're going to want these various adaptors, and helpers built on top
of them, when we replace the array-based storage of members in nominal
types and extensions with something more sane.

Lower metatype types as @thin or @thick based on whether the type is static and whether the abstraction pattern allows for a thin metatype. Add a '@thick' attribute and require SIL metatypes to always be annotated with either '@thin' or '@thick' to distinguish them from unlowered metatypes.

If -nsstring-is-string is enabled, lower Strings in cc(c) and cc(objc) function types to NSString, and when calling them, insert calls to StringToNSString/NSStringToString to perform the bridging conversion.
This isn't quite ready for prime-time yet, because we still need to emit the inverse bridging for ObjC method thunks, and I haven't tested the IRGen end of things yet.

Assigning from Nothing to Nothing should be a no-op, not copy a junk value into the destination. Also, in move-assignment we should reset the source (and thereby call the destructor) instead of abandoning the source value after moving it.

Teach SILGen's CallEmission how to emit calls to an uncurry level above the natural uncurry level of the callee. Factor out a Callee object (like in IRGen) that encapsulates how to emit an abstract callee at any uncurry level. Currently only currying standalone non-generic functions works.
Swift SVN r4720
introduce the generic type parameters (which are simply type aliases
for a to-be-determined archetype type) into scope for name
lookup. We can now parse something like
func f<T, U : Range>(x : T, y : U) { }
but there is no semantic analysis or even basic safety checking (yet).

Note that I had to re-implement llvm::Optional, since it lamely requires a default constructor. At some point, I'll push a proper implementation back to LLVM.
