◆ isOnePastEndOrElementPastEnd()

bool OpaquePointer::isOnePastEndOrElementPastEnd ( ) const

This is used in Pointer::isOnePastEnd().

We cannot read from such pointers. We can of course never read from opaque pointers anyway but we diagnose one-past-the-end pointers differently.

In contrast, OpaquePointer::isOnePastEnd() only uses the past-end bit. That is used for the APValue conversion.
