Comment:

 In 35357.4.patch:

 - Adjusted did_filter to work similar to did_action to count the number of
 times a filter is called
 - Adjusted did_filter unit tests to test the number of times a filter that
 is called 1 and 2 times and one that is never called
 - Introduced filter_functions_run to count the number of functions run on
 a filter
 - Adjusted filter_functions_run unit tests to do what patch 3's unit tests
 did.
