[Webkit] Function flow for javascript JIT execution.

Just a memo for myself to remark function flow of JIT execution.

HTMLTokenizer::scriptHandler                  // start from here to handle script

    HTMLTokenizer::scriptExecution

    ScriptController::executeScript

        Completion::evaluate

            Executable::complie               // Compile script

                 Parser::parse

            bytecodegenerator::generate       // generate byte code



            Interpreter::execute

                Executable::JITCode

                Executable::GenerateJITCode   // Compile and generateJITCode

                    JIT::Compile

                JITCode::execute              // execute JIT code

return to HTMLTokenizer::scriptHandler

Now, we generated some JIT code for basic execution demand and byte code objects for whole script.
Then, we have to compile byte code objects to JIT code for executing each function in script.

CallData::Call     // Get byte code object and compile to JIT code for each call

    Interpreter::executeCall

    JITCodeforCall::executable

        Executable::generateJITCodeforCall

    JIT::Compile

    JITCode::execute

return to CallData::Call
