On `./test/regression` failure it mentions `test/results/diffs` but no such directory exists #4045

Describe the bug

I ran the regression tests and one failed. The output said I should See /ssd/github/The-OpenROAD-Project/OpenROAD/test/results/diffs for differences but this directory doesn't seem to exist.

See the following output;

Found 1 tool regression failures.

/ssd/github/The-OpenROAD-Project/OpenROAD/test/results does exist.

Expected Behavior

The directory /ssd/github/The-OpenROAD-Project/OpenROAD/test/results/diffs exists?

@mithro, The regression gets fail/pass status by two main checks:

  1. If their log output is the same
  2. If the flow metrics are within a safety margin

If the logs differ, then the diff file is created. If the metrics fail (in your case), the failing metrics are printed in the console, for example:

jpeg_sky130hs (tcl) *FAIL* RSZ::max_slew_slack -19% <   0% ; DRT::max_slew_slack -17% < -14%

The failing metrics are two:

Currently, we do not keep track of different failure modes (1. vs 2., above). So we print the message to see the diff file whenever there's an error.
