This protects all accesses to the frame property table with a bit stored on the frame. This means we avoid hashtable operations when asking about frame properties on frames that have no properties. The changes to RestyleManager, and the new HasSkippingBitCheck API, are needed because RestyleManager depended on being able to ask for properties on a deleted frame (knowing that the property in question could not have been set on any new frames since the deleted frame was destroyed), in order to use the destruction of the properties that happens at frame destruction as a mechanism for learning that the frame was destroyed. The changes there preserve the use of that mechanism, although it becomes a bit uglier. The ugliness is well-deserved.
