RFR: 8013117: Thread-local trace_buffer has wrong type and name

[Rickard Bäckman]

Hi all,

can I have a couple of reviews for this small change. The short story is that the current way the thread-local _trace_buffer is somewhat inflexible.
By changing the type of the getter this structure gets more flexible for different implementations. I also think that the name is misused. Just naming it
to _trace_data is more generic and less implementation-specific.

The webrev: http://cr.openjdk.java.net/~rbackman/8013117/

Thanks
