    Profiler should show bytecode dumps as they would have been visible to the JITs, including the profiling data that the JITs would see

    Source/JavaScriptCore: 
    
    Adds more profiling data to bytecode dumps, and adds the ability to do a secondary
    bytecode dump for each JIT compilation of a code block. This is relevant because both
    the bytecodes, and the profiling data, may change after some number of executions.
            
    Also fixes some random dumping code to use PrintStream& rather than
    static const char[thingy].

    Tools: 
    
    Added a "profiling" (or "p") command to show the profiling data that the JITs saw
    for each JIT compilation of a code block.
            
    Also added instruction counts in the "full" display and made the "full" display the
    default thing you see.
