commit c2c4de293fdeaedc9e0fe5e02c31dd77b185d4d2
Author: Camillo Bruni <cbruni@chromium.org>
Date: Fri Jun 16 12:51:10 2017

[runtime] Handle deprecated boilerplate maps correctly

With the introduction of the fast-cloning double fields in the CSA stub for
literals we forgot to check for deprecated maps. As a result every subsequent
IC-miss would have to migrate the objects from such boilerplates.

This CL makes sure we don't use the deprecated map when copying boilerplates,
thus restoring the original behavior.
