<pre>[JSC] DFG::Node should not have its own allocator
https://bugs.webkit.org/show_bug.cgi?id=160098
Patch by Benjamin Poulain <bpoulain@apple.com> on 2016-07-25
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.
