[8u] RFR: 8230388: Problemlist additional compiler/rtm tests

[Severin Gehwolf]

Hi,

Please review this backport for cleaner hotspot tier1 runs. It adds
intermittently failing RTM tests to the newly added hotspot
ProblemList.txt file.

webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8230388/01/webrev/
Bug: https://bugs.openjdk.java.net/browse/JDK-8230388

Testing: hotspot_tier1. No more RTM failures.

Thoughts?

Thanks,
Severin
