Usage:
dg-cmp-results.sh [-v] [-v] [-v] <variant-name> <old-file> <new-file>
<variant-name> names the desired variant, "/" must be written as "\/".
Use the empty string ("") for the first variant in each file.
Output is to stdout.
Non-verbose output is degradation info like PASS->FAIL.
-v adds improvement info like FAIL->PASS.
-v -v adds info like tests that are no longer run.
-v -v -v adds info for tests that have not changed status.
-v -v -v -v is used for debugging.
