Do not abuse sese for codegeneration

Do not abuse sese for codegeneration

CLooG automatically frees the names list, so sharing SESE_PARAMS_NAMES
between gloog() and debug_generated_program() leads to freeing them
twice. As both SESE_PARAM_NAMES and SESE_PARAMS_INDEX are code
generation data structures remove them and the functions working on them
from sese.h and put them in clast-to-gimple.

	debug_clast_name_indexes_1, debug_clast_name_indexes,
	clast_name_index_elt_info, eq_clast_name_indexes): Moved from sese.h.

	gcc_type_for_clast_eq, graphite_translate_clast_equation,
	graphite_create_guard_cond_expr, graphite_create_new_loop,
	translate_clast): Add params_index.
	(initialize_cloog_names): Create parameter strings from scratch, do
	not reference other strings.
	(create_params_index): New.
	(gloog): Initialize params_index.
	* graphite-scop-detection (free_scops_1): Removed.
	(limit_scops): Use normal free_scops.
