Support iteration of the Arguments object https://bugs.webkit.org/show_bug.cgi?id=123835 Reviewed by Mark Lam. Source/JavaScriptCore: Add an ArgumentsIterator object, and associated classes so that we can support iteration of the arguments object. This is a largely mechanical patch. The only gnarliness is in the logic to avoid reifying the Arguments object in for(... of arguments) scenarios. * GNUmakefile.list.am: * JavaScriptCore.xcodeproj/project.pbxproj: * bytecompiler/BytecodeGenerator.cpp: (JSC::BytecodeGenerator::emitEnumeration): * runtime/Arguments.cpp: (JSC::Arguments::getOwnPropertySlot): (JSC::argumentsFuncIterator): * runtime/Arguments.h: * runtime/ArgumentsIteratorConstructor.cpp: Added.
