RFR: JDK-8329663: hs_err file event log entry for thread adding/removing should print current thread [v3]

[Matthias Baesken]

> Currently the entries for adding / exiting threads look like this :
> 
> Event: 81.296 Thread 0x00007fd8300c13b0 Thread added: 0x00007fd8300c13b0
> 
> Event: 81.296 Thread 0x00007fd954000fe0 Thread exited: 0x00007fd954000fe0
> 
> The hex number describing the thread is printed twice, this should be simplified or the current thread AND and added/exited thread could be printed.
