Chris Tate 2a98dbfa32 Answer constructor reads on instances without a property bag ...

The constructor read asked dyn.hasOwn on the instance's property bag, which
is undefined until the instance has one, and on the bag's prototype, so it
threw "Cannot convert undefined or null to object" for an instance without
own properties (for example `new ParseFailure('p').constructor` for a class
that extends SyntaxError). It now goes through a lifted helper that answers
false before the instance has a bag and when the bag has no prototype, as
the dyn.hasKey read did.
