  Log Message:
  -----------
  [GreedyPatternRewriter] Introduce a config object that allows controlling internal parameters. NFC.

This exposes the iterations and top-down processing as flags, and also
allows controlling whether region simplification is desirable for a client.
This allows deleting some duplicated entrypoints to
applyPatternsAndFoldGreedily.

This also deletes the Constant Preprocessing pass, which isn't worth it
on balance.

All defaults are all kept the same, so no one should see a behavior change.
