Added a profile bisection tool
This tool allows one to bisect methods in a profile to figure out
(e.g.) which one is being miscompiled. It will either take a
pre-existing profile/text-profile to start from or generate one from
the apks where every method is marked as a hot-startup method.
Usage: ./art/tools/bisect_profile.py --apk /tmp/benchmarks.dex \
--apk /tmp/ritz.jar \
--output-source bad.text-prof \
bad.prof
Test: manual
