Source/JavaScriptCore:

Adds code to support logging some hashtable stuff in the DFG.

Source/WTF:

This adds LoggingHashSet and LoggingHashMap, which are drop-in replacements for HashSet and
HashMap that log everything that they do, so that you can replay it later.

This also adds a benchmark (HashSetDFGReplay) based on doing a recording of some of the HashSets
in the DFG compiler.
