[8u20]: Request for approval - 8035394: PPC64: Make usage of intrinsic dsqrt depend on processor recognition.

[Seán Coffey]

Thanks for looking after this Vladimir. Yes - all hotspot related fixes 
should enter jdk8u via the hotspot team forest (hs-dev). Approval for 
those fixes are handled via bulk integration requests by hotspot gatekeeper.

regards,
Sean.
