Feature #7473: new events for TracePoint thread_begin/end, b_call/b_end
https://bugs.ruby-lang.org/issues/7473

Author: ko1 (Koichi Sasada)
Status: Open
Priority: Normal
Assignee: ko1 (Koichi Sasada)
Category: core
Target version: 2.0.0


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.
