Subject: [11u] RFR (S) 8223444: Improve CodeHeap Free Space Management

Hello,

Original RFE: https://bugs.openjdk.java.net/browse/JDK-8223444
Original post-fix: https://bugs.openjdk.java.net/browse/JDK-8231460

Original patch applies almost cleanly except 4 changes in
CodeHeap::add_to_freelist because JDK-8238356 is already backported,
they were applied manually.
Original post-fix (for performance issue) applies cleanly.

11u webrev: http://cr.openjdk.java.net/~dchuyko/8223444/webrev.11u.00/

Testing: tier1, tier2.
