	(switch_to_PRE_table): Likewise.
	(free_scc_vn): Do not clear SSA_NAME_VALUE.
	Do not free pre_info.
	(set_hashtable_value_ids): Do not create value-ids for the
	optimistic tables.

	in value-number printing.
	* tree-ssa-sccvn.h (switch_to_PRE_table): Remove.
	* tree-ssa-ccp.c (get_symbol_constant_value): Do not look at
	SSA_NAME_VALUE.
