[PATCH] D39269: [Analyzer] [Tests] Do not discard output from CmpRuns.py when running integration tests

Contrary to the deleted comment, in most cases CmpRuns.py produces a fairly small amount of output, which is useful to see straight away to see what has changed when executing the integration tests.
