genericValueTraversal can look through arguments and allow value simplification across function boundaries. In fact, the latter already happened unchecked. With this change we allow the user of genericValueTraversal to opt-out of interprocedural traversal if required. We explicitly look through arguments now which helps to do various things, incl. the propagation of constants into OpenMP parallel regions (on the host).
