[8u60] RFR 8069302 Deprecate Unsafe monitor methods in JDK 8u release

[Paul Sandoz]

Hi,

The Unsafe monitor methods monitorEnter. monitorExit and tryMonitorEnter were removed from JDK 9 [1].

I would like to mark those methods as deprecated in 8u60. I doubt no one will notice :-) but it's the correct thing to do.

Paul.
