bcee1df2 - SILGen: When emitting a partial application thunk for a dynamic method, convert @autoreleased result to @owned

SILGen: When emitting a partial application thunk for a dynamic method, convert @autoreleased result to @owned In IRGen, @autoreleased return values are always converted to +1 by calling objc_retainAutoreleasedReturnValue(), so a partial application thunk cannot have a result with @autoreleased convention. Just turn it into @owned instead, since that's what it is, using similar logic as the @unowned_inner_pointer => @unowned case. Fixes <rdar://problem/24805609>.
