We cannot store HeapPtrs in memory that may be realloced outside of the GC.
Instead we should use the RelocatablePtr, which is more expensive, but is able
to handle being moved, or EncapsulatedPtr which requires external barriers.

ArrayBuffers use slotSpan to store their inline size. If we try to initialize
these, then we end up with their address in the StoreBuffer, but with arbitrary
bytes written in these fields by TypeArrays. This patch uses an exact class test
to prevent this initialization behavior.
