RFR: 8341588: Remove CollectionUsageThreshold.java from ProblemList-Xcomp for debugging [v3]

[Ramkumar Sunderbabu]

> JDK-8318668 was not reproducible in repeated runs. Hence, I am pulling it out of problem listing. Additionally I have increased logging so that it is easier to debug when the issue happens again.
> 
> Testing:
> tier1,tier2,tier3
> tier6-comp,tier8-comp
