  ### Dialect Interfaces
  Dialect interfaces are generally useful for transformation passes, or analyses,
  -that want to opaquely operate on operations, even across *across* dialects.
  -These interfaces generally involve wide coverage over the entire dialect, and
  -are only used for a handful of transformations/analyses. In these cases,
  -registering the interface directly on each operation is overly complex and
  -cumbersome. The interface is not core to the operation, just to the specific
  -transformation. An example of where this type of interface would be used is
  -inlining. Inlining generally queries high level information about the operations
  -within a dialect, like legality and cost modeling, that often is not specific to
  -one operation.

  A dialect interface can be defined by inheriting from the CRTP base class
  `DialectInterfaceBase::Base`. This class provides the necessary utilities for
