bbd5dfcfdf Allow variables with a getter or setter to be declared in a 
struct/oneof/class extension, making them instance methods. Normal
variables are still not allowed in these contexts, however.

The fact that we set DeclContexts late causes some consternation here,
because it's not clear just how far we need to recurse in
DeclContext. I've done enough to make properties work, but I'm still
rather uneasy about the current state of affairs.

aa39667cae disallow destructuring a struct with a var, e.g.: 
struct point { x : int, y : int }
var (a, b) = foo()  // when foo returns a 'point'

allowing this breaks our fragility model (e.g. members can be added/removed from the struct) and this generally needs to be integrated with our pattern matching stuff.  rdar://10934540

7b29a420f6 Design and implement the [byref] attribute, checking that 
it doesn't appear in places it shouldn't.  The only limits on
this checking right now is the inadequacy of location information
for types, which is something we ought to fix.

Fix type-checking of byref applications.  Fix IR generation
of byref variables.  Whole lotta fixin' goin' on.

But hey, byref calls work.
