Enter in failing_fast mode on abort if possible.

**Describe the feature you'd like**
On an abort due an offending runner, try to execute the examples with the option ``-skip`` of other runners.

If a runner crashes or fails with an unrecoverable timeout, do not execute anything else in that language (not even parse them) but try to call the ``-skip`` examples in other languages to minimize the leaked resources (``failing_fast`` mode).

**Additional context (optional)**
Probably the feature should be implemented here:
