Remove all uses of ClassInfo for JSStrings in JIT code
https://bugs.webkit.org/show_bug.cgi?id=92935
Reviewed by Geoffrey Garen.
This is the first step in removing our dependence on in-object ClassInfo pointers
in JIT code. Most of the changes are to check the Structure, which is unique for
JSString primitives.
* bytecode/SpeculatedType.cpp:
(JSC::speculationFromClassInfo):
(JSC::speculationFromStructure): Changed to check the TypeInfo in the Structure
since there wasn't a JSGlobalData immediately available to grab the JSString
Structure out of.

Unreviewed, missed a style goof in the previous patch: "NodeIndex nodeIndex"
