I am noticing that while unnecessary casts of an EnumType to (Enum) no
longer happen, there is still a cast generated, for the EnumType itself.
Is that necessary?
E.g., I'm seeing code like this:
Fruit fruit = Fruit.APPLE;
int i = fruit.ordinal();
ending up in the AST like this (from an AST dump):
EntryPoint$Fruit fruit = EntryPoint$Fruit.APPLE;
int i = ((EntryPoint$Fruit) fruit).ordinal;
Is that extra cast necessary still? I don't think it affects
correctness, and I assume it gets optimized away later, but I wonder if
we can prevent it from getting inserted at all here.
