RFR: 8202889: Remove trailing LF from perf log

[Yasumasa Suenaga]

Hi all,

Could you review this change?

JBS: https://bugs.openjdk.java.net/browse/JDK-8202889
webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8202889/webrev.00/


JDK-8168122 introduced new UL tags for perfMemory. However they trails
unnecessary LF in each log entries.

Examples are here:

This change removes unnecessary LFs.


Thanks,

Yasumasa
