IRGen: Make outlined enum copy/destroy lazier and better mangled.

Browse Source 
Emit enum copy/destroy methods only when codegen demands them; they previously got emitted immediately when TypeInfo is instantiated, which led to many functions getting emitted that were never used. Also, make it so that the symbol name includes the full type of the enum instance the outlined functions operate on, so it's more obvious what they'e being used for and they can be ODRed across translation units.
