<pre>[JSC] Move generic data structures out of B3
https://bugs.webkit.org/show_bug.cgi?id=161155
Reviewed by Saam Barati.
Source/JavaScriptCore:
Move B3's good generic data structures to WTF.
They can be used for the other kind of basic blocks and nodes.
For example, the generator patch[1] will make BytecodeBasicBlock usable with these structures.
