Chris Lattner	2593a52b99	implement <rdar://problem/16191398> add an 'oldValue' to didSet so you can implement "didChange" properties ... This names the implicit argument "oldValue". Whether we keep implicit arguments or not is a subject of debate, tracked by rdar://16268361. Swift SVN r14819	2014-03-08 02:15:01 +00:00
Joe Groff	8e6b353542	Derive conformances of Equatable and Hashable for simple enums. ... If an enum has no cases with payloads, make it implicitly Equatable and Hashable, and derive default implementations of '==' and 'hashValue'. Insert the derived '==' into module context wrapped in a new DerivedFileUnit kind, and arrange for it to be codegenned with the deriving EnumDecl by adding a 'DerivedOperatorDecls' array to NominalTypeDecls that gets visited at SILGen time.
