Re-landing: ES6: Implement RegExp.prototype[@@search].
https://bugs.webkit.org/show_bug.cgi?id=156331
Reviewed by Keith Miller.
Source/JavaScriptCore:
What changed?
1. Implemented search builtin in RegExpPrototype.js.
The native path is now used as a fast path.
2. Added DFG support for an IsRegExpObjectIntrinsic (modelled after the
IsJSArrayIntrinsic).
3. Renamed @isRegExp to @isRegExpObject to match the new IsRegExpObjectIntrinsic.
4. Change the esSpecIsRegExpObject() implementation to check if the object's
JSType is RegExpObjectType instead of walking the classinfo chain.
