Tests that the GC doesn't mistake non-pointer constant pool entries as pointers.

Adds a test for ConstantPoolArray to ensure that the GC
doesn't mistake non-pointer entries as pointers and try
to modify them during scavenge operations.

Also adds asserts to ConstantPoolArray::set(int, *Object) to
ensure we don't add new-space pointers in constant pool
