  Log Message:
  -----------
  [mlir] move if-condition propagation to a standalone pass (#150278)

This offers a significant speedup over running this as a
canonicalizaiton pattern, up to 10x improvement when running on large
(>100k operations) inputs coming from Polygeist.

It is also not clear whether this transformation is a reasonable
canonicalization as it performs non-local rewrites.
