graphite: Rename isl_id_for_ssa_name

Browse Source 
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.cc (isl_id_for_ssa_name): Rename to ...
	(isl_id_for_parameter): ... this new function name.
	(build_scop_context): Adjust function use.
