[ko1 (Koichi Sasada)]

On the trunk, there are new 4 events for TracePoint.

* vm_trace.c: add events
  * :thread_begin - hook at thread beggining.
  * :thead_end - hook at thread ending.
  * :b_call - hook at block enter.
  * :b_return - hook at block leave.
  This change slow down block invocation.
  Please try and give us feedback until 2.0 code freeze.

b_call and b_return are proposed at [Feature #6649].

On my environment, b_call/b_return cause 15% speed-down with
null block invocation micro-benchmark.

Please try and give us feedback.
It is easy to revert until code freeze.
