Reviewed by Michael Saboff.

Make the enabled profiler a member of JSGlobalData, and switch code that accesses it to do so directly
via the JSGlobalData, rather than holding a Profiler** reference to it. Do not pass the Profiler**
reference to JIT code. This patch does not change the stack layout on entry into JIT code (passing an
unused void* instead), since this is an intrusive change better handled in a separate patch.
