tree-ssa-operands.c (get_expr_operands): Do not handle INDIRECT_REFs in the handled-component case.

2009-05-29  Richard Guenther  <rguenther@suse.de>

	* tree-ssa-operands.c (get_expr_operands): Do not handle
	INDIRECT_REFs in the handled-component case.  Remove
	unused get_ref_base_and_extent case.
	* tree-dfa.c (get_ref_base_and_extent): Avoid calling
	tree_low_cst and host_integerp where possible.
	* tree-ssa-structalias.c (equiv_class_label_eq): Check hash
	codes for equivalence.
	* dce.c (find_call_stack_args): Avoid redundant bitmap queries.
