[tests] Split corelib{,_2}/list_concurrent_modify_test
Splitting out a failing test to increase coverage of other tests. It is not clear that `a.addAll(a)` should throw if `a` is empty. `a` is not modified by the action. dart2js/DDC do not detect this case and I'm reluctant to add a check for the case where `a` is in fact not modified. The VM test is very specific to an identical argument and cannot detect the case for `a = Mylist([])`. Another option to this proposal is to simply delete the `[]` case. In general, I'd like to move more ConcurrentModificationError tests into assert statements.
