Mainline merge as of 2003-04-06. Additional fixes for bugs

exposed by the merge:

gcc/ChangeLog.tree-ssa:

	* gimplify.c (simplify_expr): Handle VECTOR_CST nodes.
	* tree-cfg.c (make_blocks): Ignore empty statement containers.
	Create a basic block before processing containers that only have
	empty statements.
	(make_loop_expr_blocks): Use the container instead of the statement
	when setting NEXT_BLOCK_LINK.
	(make_cond_expr_blocks): Likewise.
	(make_switch_expr_blocks): Likewise.
	(make_bind_expr_blocks): Likewise.
	(successor_block): If the last statement of the block is the empty
	statement, use its container to get NEXT_BLOCK_LINK.
	(stmt_starts_bb_p): Return false if the statement is NULL.
	* tree-pretty-print.c (dump_generic_node): Handle VECTOR_CST nodes.
	* tree-simple.c (is_simple_const): Accept VECTOR_CST as constants.
	* objc/objc-lang.c (LANG_HOOKS_TREE_INLINING_TREE_CHAIN_MATTERS_P):
	Define.
