Uday Bondhugula b1d9cc4d1e Extend/complete dependence tester to utilize local var info. ... - extend/complete dependence tester to utilize local var info while adding access function equality constraints; one more step closer to get slicing based fusion working in the general case of affine_apply's involving mod's/div's. - update test case to reflect more accurate dependence information; remove inaccurate comment on test case mod_deps. - fix a minor "bug" in equality addition in addMemRefAccessConstraints (doesn't affect correctness, but the fixed version is more intuitive). - some more surrounding code clean up - move simplifyAffineExpr out of anonymous AffineExprFlattener class - the latter has state, and the former should reside outside.
