* src/ast.h: * src/parser.cc: Differentiate between the different kinds of yields, in anticipation of boxing return values. Parse `return' into `yield' in a generator. * src/runtime.h: * src/runtime.cc (Runtime_SuspendJSGeneratorObject): New horrible runtime function: saves continuation, context, and operands into the generator object. * src/arm/full-codegen-arm.cc (VisitYield): * src/ia32/full-codegen-ia32.cc (VisitYield): * src/x64/full-codegen-x64.cc (VisitYield): Arrange to call SuspendJSGeneratorObject. If the call returns the hole, we suspend. Otherwise we resume. BUG=v8:2355 TEST=These codepaths are tested when the generator is first invoked, and so are covered by mjsunit/harmony/generators-objects.js.
