Layout constraints are only allowed inside '_specialize' attributes

Using Swift
1

we cannot do this:

extension BSONBinaryEncodable 
   where Self:RandomAccessCollection, Element:_Trivial
{
}
// error: layout constraints are only allowed inside '_specialize' attributes

but we are allowed to do this:

extension BSONBinaryEncodable 
    where Self:RandomAccessCollection, Element:AnyObject 
{
}

isn’t AnyObject a layout constraint?
