gabadie@chromium.org changed reviewers:
+ pasko@chromium.org

[gabadie, 2016-06-01 14:58:11]

Named sandwich_prefetch.py instead of sandwich_prefetch_builder.py for
consistency with sandwich_swr.py, but also for avoiding to long module names on
the import and use in other modules.

Named sandwich_utils.py instead of sandwich_common_utils.py for name shortening
as well.
