dirstate-v2: add test that shows a collision in ignore patterns hash...

dirstate-v2: add test that shows a collision in ignore patterns hash This hash is used for optimizing dirstate `status`. We demonstrate that the hash is incorrectly ignoring the changes to the semantics of the ignore files just because the contents (but not their source) haven't changed. This is fixed in the next changeset.
