Remove pattern_sim and partial_sim

Use of these programs has been following this pattern for several years:

1. Neglect
2. Once yearly attempt by someone to use either tool
3. Discovery that it's totally broken
4. Bug report and fast bug fix
5. Go to 1.

For more discussion, see the issue referenced below.
