Issue Description:

I'm not sure if this is intentional or not.

When conforming to CaseIterable, an Enum has a 'class style' function generated called AllCases. It doesn't produce a compile or warning and is an empty array.

Reproduction steps:

enum Direction: Int, CaseIterable {
  case north = 0, east, south, west
} 

func example() {
  let allDirections: [Direction] = Direction.AllCases()
  print(allDirections.count) // is 0
}

AllCases is the associated type; allCases is the property.
