Added a series of optimizations to the Intersect function of PresburgerRelation, referring to the ISL implementation. Tested it on a simple Benchmark implemented by myself to see that it can speed up the Intersect operation The Benchmark can be found here:https://github.com/gilsaia/llvm-project-test-fpl/blob/develop_benchmark/mlir/benchmark/presburger/Benchmark.cpp The overall results for Intersect are as follows {F28191553} The results for each case are as follows {F28191556} Reviewed By: Groverkss Differential Revision: https://reviews.llvm.org/D154771
