tree-scalar-evolution.c (chrec_contains_symbols_defined_in_loop): Use is_gimple_min_invariant instead of TREE_INVARIANT.

Browse source 
2008-03-21  Richard Guenther  <rguenther@suse.de>

	* tree-scalar-evolution.c (chrec_contains_symbols_defined_in_loop):
	Use is_gimple_min_invariant instead of TREE_INVARIANT.
	* tree-ssa-loop-ivopts.c (force_expr_to_var_cost): Likewise.
	* tree-ssa-dom.c (record_equality): Likewise.
	* tree-inline.c (copy_body_r): Likewise.
	* tree-ssa-pre.c (make_values_for_stmt): Remove test for
	TREE_INVARIANT.
