Allow ivars movement in too_complex RCLASSes to fix crash
Previously, because gc_update_object_references() did not update the
VALUEs in the too_complex ivar st_table for T_CLASS and T_MODULE
objects, GC compaction could finish with corrupted objects.
- start with `klass`, not too_complex
- GC incremental step marks `klass` and its ivars
- ruby code makes `klass` too_complex
- GC compaction runs and move `klass` ivars, but because `klass` is
too_complex, its ivars are not updated by gc_update_object_references(),
leaving T_NONE or T_MOVED objects in the ivar table.
