Subject: * vm_trace.c: add two methods:   (1) TracePoint#return_value which
 returns return   value on the :return and :c_return event.   (2)
 TracePoint#raised_exception which returns raised exception   value on the
 :raise event.   Eeach methods raise RuntimeError if it is called at
 unsupported   event.   Please review and give us feedback until next preview 
  release (Dec/2012) of Ruby 2.0.0. * insns.def, vm.c, vm_eval.c,
 vm_insnhelper.c, eval.c, thread.c:   ditto. * vm_trace.c, vm_core.h: move
 definition of rb_trace_arg_t from   vm_trace.c to vm_core.h.   Caller fills
 rb_trace_arg_t and pass the pointer of this variable. *
 test/ruby/test_settracefunc.rb: fix tests to test this change.
