JDK-8272773 introduced a configurable card table size. Some enum constants were converted to statics.

Keeping their naming the same as before, they now contradict accepted coding style guidelines, e.g.

class ObjectStartArray {
  static uint block_shift;
  [...]
}

class CardTable {
  static uint  card_shift;
  [...]
}

and so on.

Change the code to use getters as expected for those.
