Kristof Beyls e3e438a4cd Mark that SpeculativeExecution preserves Globals Alias Analysis. ... A few benchmarks with lots of accesses to global variables in the hot loops regressed a lot since r266399, which added the SpeculativeExecution pass to the default pipeline. The problem is that this pass doesn't mark Globals Alias Analysis as preserved. Globals Alias Analysis is computed in a module pass, whereas SpeculativeExecution is a function pass, and a lot of passes dependent on the Globals Alias Analysis to optimize these benchmarks are also function passes. As such, the Globals Alias Analysis information cannot be recomputed between SpeculativeExecution and the following function passes needing that information. SpeculativeExecution doesn't invalidate Globals Alias Analysis, so mark it as such to fix those performance regressions.
