<h3>Log Message</h3>
<pre>Move JSMap/JSSet over to Auxiliary MarkedSpace
https://bugs.webkit.org/show_bug.cgi?id=161744
Reviewed by Saam Barati.
Source/JavaScriptCore:
This moves the buffer out of CopiedSpace and into Auxiliary MarkedSpace.
Also removes MapData.h/MapDataInlines.h since they are not used anywhere, but they still
speak of CopiedSpace.
This is a purely mechanical change.
* JavaScriptCore.xcodeproj/project.pbxproj:
* heap/CopyToken.h:
* runtime/HashMapImpl.cpp:
(JSC::HashMapImpl<HashMapBucket>::visitChildren):
