[9] RFR(XS): 8172884: TraceOptoPipelining and TraceOptoOutput are broken

[Tobias Hartmann]

Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8172884
http://cr.openjdk.java.net/~thartmann/8172884/webrev.00/

While debugging another issue, I noticed that the TraceOptoPipelining and TraceOptoOutput flags have no effect when specified on the command line because the Compiler Control code does not set the default values according to the flag value (it works when specified as a directive). I also noticed that DoReserveCopyInSuperWordDebug is not used.

Tested manually and with RBT (running).

Thanks,
Tobias
