7089625: G1: policy for how many old regions to add to the CSet (when young gen is fixed) is broken Summary: When refactoring the code for a previous fix, a condition was not correctly negated which prevents the G1 policy from adding the correct number of old regions to the CSet when the young gen size is fixed. The changeset also fixes a small syntactical issue in g1ErgoVerbose.hpp which is causing compiler warnings. Reviewed-by: brutisso, ysr
