This is a reapplication of https://codereview.chromium.org/2809583002/ with a fix for the AOT case. We have been using IC data for receiver type info in the PolymorphicInstanceCallInstr. This is a data structure optimized for access from hand-coded assembly stubs, and placed on the GC-ed heap, which means it has to be accessed through handles. With this change we move it to the zone memory, which means it can be freed without an old-gen GC. As a side-effect the zone arrays use exponential growth for amortized constant space allocation instead of growing by 1 for quadratic allocation when we add classes, further reducing memory pressure.
