JSVariableObject::setRegisters currently takes two pointers to Register but registersArray should be PassOwnArrayPtr instead.

I’m surprised that either get() is required. We should make the smart pointers work for equality comparison without using the get().

Oops, no.  That's just me being careless.  We don't need to call get manually.  Will fix before landing the patch.

Oops, I need a temporary variable for this as well.  Will fix before landing.

Oh, can’t believe I missed that!
