RFR: 8154110: Update class* and safepoint* logging subsystems

[Robbin Ehn]

Hi Max,

I was just looking at these tags and thought maybe they should be split, 
nice !

I have request for the ' constraints' tag, can make it singular (without 
ending 's') ?

(there are a few other ones in plural which we also should fix)

Otherwise I think this looks good!

Thanks!
