Title: Si 6196

Added specialized implementation for filter

There is now an instrumented test checking for unnecessary object creations which the new implementation avoids, as well as a very simple correctness test under files/run

A benchmark is referenced in the JIRA issue, since AFAIK there is not yet a way to add a benchmark as a test.
