Remove individial dependence pointers and add a scop::dependence to contain all the dependence.

Removed the member variables which are only used in scop_get_dependence. Instead
only maintaining the overall dependence. Passes regtest and bootstrap.

gcc/ChangeLog:

2015-12-15  hiraditya  <hiraditya@msn.com>

        * graphite-dependences.c (scop_get_dependences): Use local pointers.
        * graphite-isl-ast-to-gimple.c(translate_isl_ast_to_gimple::scop_to_isl_ast):
          Use scop->dependence.
        * graphite-optimize-isl.c (optimize_isl): Same.
        * graphite-poly.c (new_scop): Remove initialization of removed members.
        (free_scop): Same.
        * graphite.h (struct scop): Remove individial dependence pointers and
        add a scop::dependence to contain all the dependence.
