From: Chris Lattner <sabre@nondot.org>

Subject: * Both Method & GlobalVariable now subclass GlobalValue *
 ConstPoolPointerReference now represents a pointer to a GlobalValue * Methods
 name references are now explicit pointers to methods * Rename
 Value::GlobalVal to Value::GlobalVariableVal to avoid confusion
