Crash: Add a "Test All Crash Types" option

Browse source 
Add an option "-A", that will run all of the crash types in the crash
program. In this mode, all crash tests are run in a child process so
that the crash program does not crash.

Crash uses the return status of the child process to ascertain whether
the crash happened as expected.
