Replace them with swift_cxx_newObject/swift_cxx_deleteObject to avoid calling overridden global operators. Overridden global operators can sometimes fail when called from places the authors didn't expect. The particular uses being changed here are: 1. Creation of new SingletonMetadataCacheEntry objects. 2. Allocation of the _globalIvarOffsets array in initGenericObjCClass. 3. Creation/destruction of SwiftTLSContext objects. rdar://106238547
