O_o. The submit timestamps are the same. JIRA is funky today, huh.

I thought we are better off tracking this separately, and then close
all/any pending bugs about UseCompilerSafepoints as WNF citing 8064776.
Still want to do this in 8064749?

Also, I wonder if we want to demote the flag to experimental in 8u. This
does not sound like a backport of 8064749 at all, but rather a separate
change.
