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.

Best regards,
