      Defines a partial order ('depends on' function) where `this` must occur
      before `that`.
  
      For example, the following pass list and constraint list would be invalid.
      ```
      passes = [pass_b, pass_a]
  
      constraints = [
          this_before_that_pass_constraint(pass_a, pass_b)
      ]

      Args:
          this (Callable): pass which should occur first
          that (Callable): pass which should occur later
