Hi, please see this update:
This is revert to the original, I accidental had left in a temporary test
change, as you can see here in full diff:
I think I manage to address all review comments.
Dean can you please cast an extra eye on:
This OR should be correct.
Dan please do the same on the biased locking changes.
I left out the merge with MutexLocker changes, since it was not interesting.
There were some conflicts with JVMCI changes, so incremental contains some parts
of that merge.
Passes t1-5 and local testing.
I'll continue with some additional testing.
