RFR (XS) JDK-8164482,[REDO] G1 does not implement millis_since_last_gc which is needed by RMI GC

 1. JDK-8164482 <https://bugs.openjdk.java.net/browse/JDK-8164482>[REDO]
    G1 does not implement millis_since_last_gc which is needed by RMI GC

Tests:  JPRT.  Also, I put in a log message for testing.  It calls 
millis_since_last_gc() before each collection.  This will be removed 
before pushing.  The messages printed show millis since last gc always 
 >= 0 and the warning message is never printed.

thanks.
