Bug 37869 – Move URopeImpl to its own .h/.cpp.

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Gavin Barraclough]

Currently Ropes are implemented by the class URopeImpl, which is defined in UStringImpl.h, and then typedefed to the name JSString::Rope.

Remove the typedef, and rename all uses of URopeImpl and JSString::Rope to just RopeImpl.

Move RopeImpl to its own header, and remove all remaining references to ropes from UStringImpl (rename UStringOrRopeImpl to UStringImplBase, rename or move the isRope & deref methods from UStringOrRopeImpl).

The patch

+    bool isInvalid() { return (m_refCountAndFlags & s_refCountInvalid) == s_refCountInvalid; }

Let's reverse the meaning of this function, and call it "isStringImpl". And also give an appropriate name to s_refCountInvalid.
