I kind of think a better name would be G1YoungPhase - the C in that name is an abbreviation for "collection", and to me, YCPhase indicates the phases in the collection which this is not.
Better names are certainly possible.
Please also add some small documentation, like "The phases the collection cycle can be in".

Not sure if it might be better to name this G1PauseType since Cleanup and Remark aren't really collections. But maybe it's fine as is (or G1GCPauseType if you prefer).

This should probably be 2012, 2021, - I do not see a reason to remove the former date.

webrev shows this as a new file, while github shows it as a renamed file. Not sure which one to consider.

These three asserts could probably be moved into a helper method as the exact same code is used in is_mixed_pause() too. Your call.

is_young_pause_young_only()? Just to match the method. Feel free to ignore.

I think adding the assert_is_young_pause should remove the need to add is_young_pause prefix to these methods.

is_young_pause_concurrent_start(). Same as above, it should have the three asserts.
