[RFA 1/8] validate_failures.py: add TestResult ordinal

[RFA 1/8] validate_failures.py: add TestResult ordinal

[Doug Evans]

Hi.
This set of 8 patch makes some minor tweaks to validate_failures.py,
and provides some new functionality.
They are relatively independent, but the patches are intended to be applied in order.

This first patch adds an ordinal to TestResult so that the sorting
keeps the tests in order of appearance.

Ok to check in?
