bondhugula retitled this revision from "[MLIR] add flat affine constraints method to round trip integer set" to "[MLIR] Add flat affine constraints method to round trip integer set".

- add method to get back an integer set from flat affine constraints; this allows a round trip
- use this to complete the simplification of integer sets in -simplify-affine-structures
- update FlatAffineConstraints::removeTrivialRedundancy to also do GCD tightening and normalize by GCD (while still keeping it linear time).
