RFR: JDK7 Backport of JDK-8058583: Remove CompilationRepeat

[Andreas Eriksson]

Hi,

Please review this jdk7 backport of JDK-8058583 which removes the 
compilation repeat flag.
The only difference to the jdk8 changeset is that the obsolete version 
for the flag is 7u80, not 8.

For reference:
JDK8 changeset: 
http://hg.openjdk.java.net/jdk8u/hs-dev/hotspot/rev/b9c94af14fd0

Regards,
Andreas
