Description
In testing a tiered jvm I noticed that we bias revocation during OSR or uncommon traps if we find any locked objects. We only need to do the revocation if the objects are biased locked.

Comments
EVALUATION Need to check the objects to see if they are biased before requesting a safepoint and doing the revocation.
