John Hawthorn 19f331f588 Dedup superclass array in leaf sibling classes ... Previously, we would build a new `superclasses` array for each class, even though for all immediate subclasses of a class, the array is identical. This avoids duplicating the arrays on leaf classes (those without subclasses) by calculating and storing a "superclasses including self" array on a class when it's first inherited and sharing that among all superclasses. An additional trick used is that the "superclass array including self" is valid as "self"'s superclass array. It just has it's own class at the end. We can use this to avoid an extra pointer of storage and can use one bit of a flag to track that we've "upgraded" the array.		2022-03-03 11:23:27 -08:00
