6814437: G1: remove the _new_refs array
Summary: The per-worker _new_refs array is used to hold references that point into the collection set. It is populated during RSet updating and subsequently processed. In the event of an evacuation failure it processed again to recreate the RSets of regions in the collection set. Remove the per-worker _new_refs array by processing the references directly. Use a DirtyCardQueue to hold the cards containing the references so that the RSets of regions in the collection set can be recreated when handling an evacuation failure.

2 OPENJDK ASSEMBLY EXCEPTION
4 The OpenJDK source code made available by Oracle at openjdk.java.net and
5 openjdk.dev.java.net ("OpenJDK Code") is distributed under the terms of the
6 GNU General Public License <http://www.gnu.org/copyleft/gpl.html> version 2
7 only ("GPL2"), with the following clarification and special exception.
9 Linking this OpenJDK Code statically or dynamically with other code
10 is making a combined work based on this library. Thus, the terms
11 and conditions of GPL2 cover the whole combination.
13 As a special exception, Oracle gives you permission to link this
14 OpenJDK Code with certain code licensed by Oracle as indicated at
15 http://openjdk.java.net/legal/exception-modules-2007-05-08.html
16 ("Designated Exception Modules") to produce an executable,
17 regardless of the license terms of the Designated Exception Modules,
18 and to copy and distribute the resulting executable under GPL2,
19 provided that the Designated Exception Modules continue to be
20 governed by the licenses under which they were offered by Oracle.
22 As such, it allows licensees and sublicensees of Oracle's GPL2 OpenJDK Code to
23 build an executable that includes those portions of necessary code that Oracle
24 could not provide under GPL2 (or that Oracle has provided under GPL2 with the
25 Classpath exception). If you modify or add to the OpenJDK code, that new
26 GPL2 code may still be combined with Designated Exception Modules if the
27 new code is made subject to this exception by its copyright holder.
