[polly] r309878 - Enable simplify and forward-op-tree by default

Log:
Enable simplify and forward-op-tree by default

These passes have been tested over the last month and should generally help
to remove scalar data dependences in Polly. We enable them to give them even
wider test coverage. Large performance regressions and any kind of correctness
regressions are not expected.
