  Log Message:
  -----------
  [mlir][SCF] Do not peel loops inside partial iterations

Do not apply loop peeling to loops that are contained in the partial iteration of an already peeled loop. This is to avoid code explosion when dealing with large loop nests. Can be controlled with a new pass option `skip-partial`.
