Transition shape when object's capacity changes
This commit adds a `capacity` field to shapes, and adds shape transitions whenever an object's capacity changes. Objects which are allocated out of a bigger size pool will also make a transition from the root shape to the shape with the correct capacity for their size pool when they are allocated. This commit will allow us to remove numiv from objects completely, and will also mean we can guarantee that if two objects share shapes, their IVs are in the same positions (an embedded and extended object cannot share shapes). This will enable us to implement ivar sets in YJIT using object shapes. Co-Authored-By: Aaron Patterson <[email protected]>
