This pass converts GIMPLE to GRAPHITE, performs some loop
   transformations and then converts the resulting representation back
   to GIMPLE.

   An early description of this pass can be found in the GCC Summit'06
   paper "GRAPHITE: Polyhedral Analyses and Optimizations for GCC".
   The wiki page http://gcc.gnu.org/wiki/Graphite contains pointers to
   the related work.

   One important document to read is CLooG's internal manual:
   http://repo.or.cz/w/cloog-ppl.git?a=blob_plain;f=doc/cloog.texi;hb=HEAD
   that describes the data structure of loops used in this file, and
   the functions that are used for transforming the code.
