Lowercase enum constant names get uppercased

[Runemoro]

Even after liach's enum constant PR, enum constant names don't match their .name() if the name is lowercase (see class_4396$class_4397). This causes problems with Procyon (or at least, an older version of it), and would also break anything relying on valueOf if the code is recompiled.

Good point. I will look into fixing that.
