Refactor graphite-sese-to-poly, sese.h, graphite-poly.h

Now that scop contains a list of all the basic blocks inside, it makes sense to
iterate over only those basic blocks in
graphite-sese-to-poly.c:rewrite_reductions_out_of_ssa,rewrite_cross_bb_scalar_deps_out_of_ssa

Passes regtest and bootstrap.

gcc/ChangeLog:

2015-10-20  Aditya Kumar  <hiraditya@msn.com>

        * graphite-poly.h (struct dr_info): Added invalid_alias_set number.
        (operator=): Removed.
        (dr_info): Make alias_set number the last argument with default value of invalid_alias_set.
        * graphite-sese-to-poly.c (build_scop_drs): Update constructor of dr_info.
        (rewrite_reductions_out_of_ssa): Iterate only through the basic blocks which are inside region.
        (rewrite_cross_bb_scalar_deps_out_of_ssa): Same.
        * sese.h (struct sese_l): Removed assignment operator.
        (split_region_for_bb): Removed dead code.
