merges r32334 and r32335 from trunk into ruby_1_9_2.

--
* vm_insnhelper.c (vm_call_bmethod): fix to hook call/return event
  for methods defined by define_method().
* thread.c (call_trace_proc): Fix to skip if class is not given (0).
  Note that ID and Class object are passed for call/return event
  if the called method was defined by define_method().
  If you are author of tracer/profiler/debugger, this may be an
  important change.  You should check passed class as zero or
  non-zero instead of checking the event type.
* test/ruby/test_settracefunc.rb: add a test for above.
