class FieldValueFilter in Drupal 7 to 8/9 Module Upgrader 8

Filters for things that *look like* field accesses, e.g. $foo->bar[LANGUAGE_NONE][0]['value']. This filter doesn't guarantee that matched nodes actually ARE field accesses -- just that they have the proper formation (S-foils in attack formation!...what, you don't like Star Wars?)
