Integrate built-in bisection search with runtest

Adds a --bisection-search switch to run-test. When this switch
is enabled run-test performs bisection bug search for nonchecker
failing tests attempting to find faulty method and optimization.

Adds ART_TEST_BISECTION flag support to Android.run-test.mk.
When this flag is set to true, run-test will run in bisection
search mode.

Bisection search works in no-prebuild mode only.

Test: ART_TEST_BISECTION=true m test-art-run-test
