Usage: remove-fixed-failures.sh possible-fixes.log failures.log

possible-fixes.log contains the possible fixes from the most recent
test run.

failures.log contains the current known failures.

remove-fixed-failures.sh removes each pattern in possible-fixes.log
from failures.log.

The original failures.log is saved as failures.log.orig for safe keeping.
