RFR(S): 8151637: Move CollectionSetChooser rebuild code into CollectionSetChooser

[Jon Masamitsu]

A couple of copyright updates needed.

http://cr.openjdk.java.net/~mgerdin/8151637/webrev.0/src/share/vm/gc/g1/collectionSetChooser.cpp.frames.html
http://cr.openjdk.java.net/~mgerdin/8151637/webrev.0/src/share/vm/gc/g1/collectionSetChooser.hpp.frames.html

Otherwise, looks good.
