Hi grosser, sebpop, dpeixott, simbuerg, zinob,

  This commit drops the Cloog support for Polly. The scripts and
  documentation are changed to only use isl as prerequisity. In the code
  all Cloog specific parts have been removed.

  TODO: This commit removes all Cloog tests, however, we should port
        them to the isl backend.
