  -----------
  [mlir][Transforms] Simplify region before simplifying operation in CSE.

This covers more options for CSE. It also ensures that two operations
that have same operands but different regions to begin with, but same
regions after `simplifyRegions`, don't get both added to the list of
`knownValues`.

Fixes #59135
