This change introduces syncLockOpr like the existing syncTempOpr. Other platforms than PPC64 just return a new register so it's no functional change there.
This change is a prerequisite for our C1 on PPC64 contribution.
Webrev is here:
Implementation for aarch64 is included but not tested.
Please review this change. I need a sponsor, please.
