[turbofan] General consolidation of element access. Avoid TransitionElementsKind when storing to objects which only differ in holeyness of their elements kind. Instead go for polymorphic CheckMaps, which can often by optimized and avoid the mutation of the array map. This generalizes the approach https://codereview.chromium.org/2836943003 which covered only element loads.
