These Android-specific results will be added to
external/webkit/LayoutTests/platform/android-<js-engine> and are used in
preference to the generic expected results.
The JavaScript engine to use is read from the JS_ENGINE environment variable
used by the build system or can be overridden on the command line. If neither
is set, it defaults to JSC.

1) Lab machines can run layout tests without having build environment setup
2) We could have different set of pass/fail results per branch
Also added a simple python script which runs run_layout_tests.py
