Jakob Kummerow a3ef2489f2 Cache fewer StoreIC-Transition handlers 
Many handlers are not used again, so we can improve the cache hit rate
by caching fewer handlers. Specifically, in this CL, when a StoreIC
miss causes a new map transition to be created, then the handler is not
cached right away yet (it will be cached next time, when the transition
exists already).

Also, fix an embarrassing bug where growing a TransitionArray dropped
cached handlers. That further improves the cache hit rate. ;-)
