Add bionic-stress-tests.
I plan to add tests to this test binary that take a long time to run.
The first is a malloc test that demonstrates that jemalloc appears
to be leaking memory slowly over time.
Test: Ran the bionic-stress-tests on host and verified it runs forever,
Test: but doesn't display RSS/VSS data.
Test: Ran the bionic-stress-tests on a taimen and verified it runs forever,
Test: and does display RSS/VSS data.
