The options G1EagerReclaimHumongousObjects and G1EagerReclaimHumongousObjectsWithStaleRefs are presently defined as experimental, but are enabled by default.

The features being controlled have been enabled for a number of months without causing problems, so that we no longer consider the associated features to be experimental.  So it's time to remove the options.

There is actually an argument about not removing these options, JDK-8141637 shows that disabling eager humongous reclamation may be useful.
