re PR tree-optimization/17111 (tree check ICE in value_insert_into_set_bitmap on inlining a memcmp-like function) 

2004-08-20  Daniel Berlin  <dberlin@dberlin.org>

	Fix PR tree-optimization/17111
	* tree-ssa-pre.c (create_value_expr_from): Don't change the types
	of non-value_handles.
	(bitmap_set_contains): All constants are in every set.
