That's legal, I can write a category against an already-compiled
class without having the source and without recompiling it and I can
access any of the private variables of that class. So no the
compiler cannot throw away instance variables when it compiles the
class originally even if no method of A used them originally because
someone might go write a category against the compiled object which
needs it later.
Actually, this will not work across a module boundary on the modern
runtime because the linker will strip the symbol for the private ivar.
