LibTest: Add ability to turn test failure reporting on/off
This will be very useful as we add the randomized test cases and their
two loops ("generate+test many times" and "shrink once failure is
found"), because without this failure reporting we'd get many FAIL error
messages while still searching for the minimal one.
So, inside randomized test cases we want to only turn the error
reporting on for one last time after all the generating and shrinking.
