[turbofan] Initial version of allocation folding and write barrier elimination. This adds a new pass MemoryOptimizer that walks over the effect chain from Start and lowers all Allocate, LoadField, StoreField, LoadElement, and StoreElement nodes, trying to fold allocations into allocation groups and eliminate write barriers on StoreField and StoreElement if possible (i.e. if the object belongs to the current allocation group and that group allocates in new space).
