Fixed a few bugs in dexfuzz:
- Set error level on exit when there are divergences.
- Fix cleanCodeCache not preprending adb shell.
- Fixed clearCache.
- Fixed bug in reading end of try block.
- Fixed bug in shifting try block.
- Fixed a bug reading debug info.
Test: Extract dex files from art-tests as named below and test run commands:
dexfuzz --arm --interpreter --optimizing --repeat=2 --execute --input=seeds/068-classloader.dex
dexfuzz --arm --interpreter --optimizing --repeat=2 --execute --input=seeds/510-checker-try-catch.dex
You should not get errors.

Integrate dexfuzz with bisection search
Adds --bisection-search switch to dexfuzz. When specified makes
dexfuzz run bisection search on discovered output divergences.
Bisection search output is saved to bisection_outputs/ directory which
is assumed to be present.
If --bisection-search is used, bisection_search.py has to be on PATH.
Test: ./run_dex_fuzz_test.py , with hardcoded change to emit a known
divergent program instead of calling jfuzz.

Remove fuzzer build-time dependency on core image.
Test if the image exists at runtime.
Forcing this dependency slows down development. For example, if after a
change dex2oat does not compile anymore you need to first revert to a
stable state and rebuild the core image to be able to move foreward.
Since this is a test tool, it is ok to assume that the core image has
already been built if host execution was selected.

Adds host execution to dexfuzz.
Use --host to execute fuzzed tests using the host-build of ART.
See the README for more information.
Also includes some refactoring of Executors/Devices.

Adds the dexfuzz fuzzing tool to ART.
This tool can mutate DEX files, and execute them with multiple backends
of ART, making sure that all backends agree on the output of the
program. This should help identify bugs in particular backends, should
they produce output that disagrees with the other backends.
Build with mmm tools/dexfuzz from within art/.
See the README for details about how to use dexfuzz.
