[region-isolation] Make temporary alloc_stack that we form for returning values from a non-final class field take on the class method's isolation. The reason why we are doing this is that otherwise, we have that the alloc_stack formed for the result is disconnected and despite the fact that we merge it into the actor region of the class method, we do not have that the alloc_stack specifically is marked when we attempt to squelch Please. This patch fixes that problem by detecting when an alloc_stack is being used as a temporary for an out parameter and makes the alloc_stack initially isolated as appropriate. It only does this in the specific cases where we can pattern match it which in my limited testing has handled everything.
