[10] RFR: 8185796: jstack and clhsdb jstack should show lock objects

[Yasumasa Suenaga]

Hi all,

Thread dump shows lock objects, however jstack jhsdb and jstack in CLHSDB are not show them.
They are very useful for checking monitors. So jstack mode should show them.

I uploaded webrev. Could you review it?

This change prints locked stack looks like:

* jhsdb jstack
----------------
"main" #1 prio=5 tid=0x00007f1844018800 nid=0xe7f0 waiting on condition [0x00007f184df31000]
    java.lang.Thread.State: TIMED_WAITING (sleeping)
    JavaThread state: _thread_blocked
  - java.lang.Thread.sleep(long) @bci=0 (Interpreted frame)
  - LongLock.main(java.lang.String[]) @bci=8, line=4 (Interpreted frame)
     - locked <0x00000000dfc13b28> (a java.lang.Class)
----------------

* jstack in CLHSDB
----------------
"main" #1 prio=5 tid=0x00007f1844018800 nid=0xe7f0 waiting on condition [0x00007f184df31000]
    java.lang.Thread.State: TIMED_WAITING (sleeping)
    JavaThread state: _thread_blocked
  - java.lang.Thread.sleep(long) @bci=0 (Interpreted frame)

     - locked <0x00000000dfc13b28> (a java.lang.Class)

I cannot access JPRT.
So I need a sponsor.
