  The SSA names for which this function gets used are always SCoP
parameters and hence "isl_id_for_parameter" is a better name.  It also
explains the prefix "P_" for those names in the ISL representation.

gcc/ChangeLog:

        * graphite-sese-to-poly.c (isl_id_for_ssa_name): Rename to ...
          (isl_id_for_parameter): ... this new function name.
          (build_scop_context): Adjust function use.

Rediffed Frederik's patch. Actual change is just s/.c/.cc/ but also a
missing space → tab.
