Do not check all GEPs for assumptions Before, we checked all GEPs in a statement in order to derive out-of-bound assumptions. However, this can not only introduce new parameters but it is also not clear what we can learn from GEPs that are not immediately used in a memory accesses inside the SCoP. As this case is very rare, no actual change in the behaviour is expected. llvm-svn: 267442
