Adding a testcase and reverting this patch:
[PATCH] remove parameter_rename_map

This map was used in the transition to the new scop detection: with the new scop
detection, we do not need this map anymore.

       Remove use of parameter_rename_map.
       (copy_def): Remove.
       (copy_internal_parameters): Remove.
       (graphite_regenerate_ast_isl): Remove call to copy_internal_parameters.

       (set_rename): Do not use parameter_rename_map.
       (rename_uses): Update call to set_rename.
