bug 736978 - remove JS_FinalizeStub. r=:billm Currently the GC finalizes on the background thread only objects with null JSClass::finalize. However, this implies that any object that uses JS_FinalizeStub for the finalizer would be prevented from the background finalization. To fix this the patch removes JS_FinalizeStub replacing it with NULL in all cases when the class has no custom finalizer. For style consistency the patch also removed the usage of JSCLASS_NO_OPTIONAL_MEMBERS in the static declarations as the compiler fills the missing fields with null in any cases.
