title: Building v8 without JIT
body: <p>I would like to run some tests on v8 with and without JIT to compare
  performances.
  I know JIT will improve my average speed performance, but it would be
  nice for me to have some actual more detailed tests results as I want to work with mobile platforms.</p>
  
  <p>I haven't found how to enable or disable JIT like it exists on Squirrelfish (cf. ENABLE_JIT in JavaScriptCore/wtf/Platform.h).</p>
  
  <p>Does somebody knows how to do that with v8?</p>
  
  <p>Thanks.</p>
  
  <p>Alexandre</p>
