This patch changes Polly to compute the data-dependences on the schedule tree instead of a flat schedule representation. Calculating dependences directly on the schedule tree results in some good compile-time improvements (adi : -23.35%, 3mm : -9.57%), as the structure of the schedule can be exploited for increased efficiency. Earlier experiments with schedule tree based dependence analysis in Polly showed some compile-time regressions. These regressions arose due to the schedule tree based dependence analysis not taking into account the domain constraints of the schedule tree. As a result, the computed dependences were different and this difference caused in some cases the schedule optimizer to take a very long time. Since isl version fe865996 the schedule tree based dependence analysis takes domain constraints into account, which fixes the earlier compile-time issues.
