RFR: 8272788: Nonleaf ranked locks should not be safepoint_check_never

[Coleen Phillimore]

I moved nonleaf ranked locks to be leaf (or leaf+something).  Many of the leaf locks are safepoint_check_never.  Segregating this rank into safepoint checking and non-safepoint checking is left for a future RFE.
Tested with tier1-3.  Tier 4-6 testing in progress.
