Reviewers: Michael Starzinger,
Description:
Keep track of which maps are associated with prototype objects so we can
tune
the fast-case vs. hash map heuristics accordingly.
This is a reland of r11681 https://chromiumcodereview.appspot.com/10448011 ,
which was reverted because of layout test failures that were actually
caused by
the long-standing issue fixed in
https://chromiumcodereview.appspot.com/10515006
(r11706).
