IBAMR Pull Request Checklist

• Does the test suite pass?
• Was clang-format (i.e., make indent) run? For more information see
  scripts/formatting/README.md.
• Were relevant issues cited? Please remember to add Fixes #12345 to close
  the issue automatically if we are fixing the problem.
• Is this a change others will want to know about? If so, then has a
  changelog entry been added?
• If new data structures have been added to a class then have they been set
  up appropriately for restarts? If so, ensure that the restart version
  number is incremented.
• Does this change include a bug fix or new functionality? If so, a new test
  or tests should be added. New tests should run quickly (less than a minute
  in release mode). If possible, an older test should gain a new option so
  that we do not need to compile more test executables.
• Did you (if your account has permission to do so) set relevant labels on
  GitHub for the pull request?
