+ [JSC] DFG::Node should not have its own allocator
+ https://bugs.webkit.org/show_bug.cgi?id=160098
+
+ Reviewed by Geoffrey Garen.
+
+ We need some design changes for DFG::Node:
+ -Accessing the index must be fast. B3 uses indices for sets
+ and maps, it is a lot faster than hashing pointers.
+ -We should be able to subclass DFG::Node to specialize it.
