[infer failure] Missing type in object Global f: #7

In one of the stub calls we didn't go through a type barrier after a property cache hit.  This adds nativeSetSlotWithType for cases where we have the shape and associated slot but need to go through a barrier before updating the object (analogous to setDenseArrayElementWithType).  Went through other nativeSetSlot calls and there were a couple other places missing barriers.
