[libFuzzer] Add --dump-input-on-failure to help diagnose AArch64 failures [NFC]

Authored by peter.smith on Apr 30 2019, 8:03 AM.



The fork-siguser.test and fork.test intermittently fail on the AArch64 buildbot. Unfortunately these failures are not reproducible on a similar machine and seem to fail when the machines are under load so I suspect that there isn't much that can be done. Before suggesting the tests be marked unsupported for AArch64 we'd like to see if we can get some more information about the failures to see if it helps us reproduce. This patch adds --dump-input-on-failure to the FileCheck commands to see if we can get some more information about the failures. We should be able to get enough input over a couple of days and can take these out afterwards.
