After a mixed gc phase we clear the remembered sets of collection set candidates serially.
This may take a significant amount of time (BigRAMTester@50G heap@32M regions ~70ms; BigRAMTester@50G heap@1M regions ~800ms) every time at the last mixed gc in a mixed gc phase.
This started to show up with JDK13 after the refactoring inJDK-8218668 as high "Other" time, but has been a problem since introduction in JDK-8190269.
Parallelize in some way.
