  Changed paths:
    M mlir/lib/Transforms/BufferDeallocation.cpp
    M mlir/test/Transforms/buffer-deallocation.mlir

  Log Message:
  -----------
  Added check if there are regions that do not implement the RegionBranchOpInterface.

Add a check if regions do not implement the RegionBranchOpInterface. This is not
allowed in the current deallocation steps. Furthermore, we handle edge-cases,
where a single region is attached and the parent operation has no results.
