  Log Message:
  -----------
  [GreedPatternRewriter] Preprocess constants while building worklist when not processing top down

This avoids accidentally reversing the order of constants during successive
application, e.g. when running the canonicalizer. This helps reduce the number
of iterations, and also avoids unnecessary changes to input IR.

Fixes #51892
