[ES6] Implement RegExp sticky flag and related functionality https://bugs.webkit.org/show_bug.cgi?id=155177 Reviewed by Saam Barati. Source/JavaScriptCore: Implemented the ES6 RegExp sticky functionality. There are two main behavior changes when the sticky flag is specified. 1) Matching starts at lastIndex and lastIndex is updated after the match. 2) The regular expression is only matched from the start position in the string. See ES6 section 21.2.5.2.2 for details. Changed both the Yarr interpreter and jit to not loop to the next character for sticky RegExp's. Updated RegExp exec and match, and stringProtoFuncMatch to handle lastIndex changes. Restructured the way flags are passed to and through YarrPatterns to use RegExpFlags instead of individual bools. Updated tests for 'y' flag and new behavior. * bytecode/CodeBlock.cpp: (JSC::regexpToSourceString): * inspector/ContentSearchUtilities.cpp: (Inspector::ContentSearchUtilities::findMagicComment): * runtime/CommonIdentifiers.h: * runtime/RegExp.cpp: (JSC::regExpFlags): (JSC::RegExpFunctionalTestCollector::outputOneTest): (JSC::RegExp::finishCreation): (JSC::RegExp::compile): (JSC::RegExp::compileMatchOnly): * runtime/RegExp.h: * runtime/RegExpKey.h: * runtime/RegExpObjectInlines.h: (JSC::RegExpObject::execInline): (JSC::RegExpObject::matchInline): * runtime/RegExpPrototype.cpp: (JSC::regExpProtoFuncCompile): (JSC::flagsString): (JSC::regExpProtoGetterMultiline): (JSC::regExpProtoGetterSticky): (JSC::regExpProtoGetterUnicode): * runtime/StringPrototype.cpp: (JSC::stringProtoFuncMatch): * tests/es6.yaml: * tests/stress/static-getter-in-names.js: (shouldBe): * yarr/RegularExpression.cpp: (JSC::Yarr::RegularExpression::Private::compile): * yarr/YarrInterpreter.cpp: (JSC::Yarr::Interpreter::tryConsumeBackReference): (JSC::Yarr::Interpreter::matchAssertionBOL): (JSC::Yarr::Interpreter::matchAssertionEOL): (JSC::Yarr::Interpreter::matchAssertionWordBoundary): (JSC::Yarr::Interpreter::matchDotStarEnclosure): (JSC::Yarr::Interpreter::matchDisjunction): (JSC::Yarr::Interpreter::Interpreter): (JSC::Yarr::ByteCompiler::atomPatternCharacter): * yarr/YarrInterpreter.h: (JSC::Yarr::BytecodePattern::BytecodePattern): (JSC::Yarr::BytecodePattern::estimatedSizeInBytes): (JSC::Yarr::BytecodePattern::ignoreCase): (JSC::Yarr::BytecodePattern::multiline): (JSC::Yarr::BytecodePattern::sticky): (JSC::Yarr::BytecodePattern::unicode): * yarr/YarrJIT.cpp: (JSC::Yarr::YarrGenerator::matchCharacterClass): (JSC::Yarr::YarrGenerator::jumpIfCharNotEquals): (JSC::Yarr::YarrGenerator::generateAssertionBOL): (JSC::Yarr::YarrGenerator::generateAssertionEOL): (JSC::Yarr::YarrGenerator::generatePatternCharacterOnce): (JSC::Yarr::YarrGenerator::generatePatternCharacterFixed): (JSC::Yarr::YarrGenerator::generateDotStarEnclosure): (JSC::Yarr::YarrGenerator::backtrack): * yarr/YarrPattern.cpp: (JSC::Yarr::YarrPatternConstructor::YarrPatternConstructor): (JSC::Yarr::YarrPatternConstructor::atomPatternCharacter): (JSC::Yarr::YarrPatternConstructor::setupAlternativeOffsets): (JSC::Yarr::YarrPatternConstructor::optimizeBOL): (JSC::Yarr::YarrPattern::compile): (JSC::Yarr::YarrPattern::YarrPattern): * yarr/YarrPattern.h: (JSC::Yarr::YarrPattern::reset): (JSC::Yarr::YarrPattern::nonwordcharCharacterClass): (JSC::Yarr::YarrPattern::ignoreCase): (JSC::Yarr::YarrPattern::multiline): (JSC::Yarr::YarrPattern::sticky): (JSC::Yarr::YarrPattern::unicode): LayoutTests: New and updated tests. * js/Object-getOwnPropertyNames-expected.txt: * js/regexp-flags-expected.txt: * js/regexp-sticky-expected.txt: Added. * js/regexp-sticky.html: Added. * js/script-tests/Object-getOwnPropertyNames.js: * js/script-tests/regexp-flags.js: (RegExp.prototype.hasOwnProperty): Deleted check for sticky property. * js/script-tests/regexp-sticky.js: New test.
