Jakob Gruber 3c422d1c5e [snapshot] Clear reconstructable data prior to d8 stress_snapshot run
The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.

With this change, mjsunit tests pass on x64.

The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.

Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.
