	* tree-cfg.c (gimplify_val): Move from tree-complex.c.
	(gimplify_build1): Move from tree-complex.c do_unop.
	(gimplify_build2): Move from tree-complex.c do_binop.
	(gimplify_build3): New.
	* tree-complex.c (gimplify_val, do_unop, do_binop): Remove.
	Adjust throughout to call the functions above.
	* tree-flow.h: Declare the functions above.
	* tree-nested.c (gimplify_val): Rename to...
	(tsi_gimplify_val): ... this.

	* Makefile.in (tree_complex.o): Update dependencies.
	(stor-layout.o): Depend on regs.h.
	* c-common.c (handle_vector_size_attribute): Update for
	vector types without corresponding vector modes.
	* expr.c (expand_expr): Treat VECTOR_CST's like CONSTRUCTORS if
	a corresponding vector mode is not available.
	* print-tree.c (print_node): Print nunits for vector types
	* regclass.c (have_regs_of_mode): New.
	(init_reg_sets_1): Initialize it and use it instead
	of allocatable_regs_of_mode.
	* regs.h (have_regs_of_mode): Declare it.
	* stor-layout.c (layout_type): Pick a mode for vector types.
	* tree-complex.c (build_word_mode_vector_type, tree_vec_extract,
	build_replicated_const, do_unop, do_binop, do_plus_minus,
	do_negate, expand_vector_piecewise, expand_vector_parallel,
	expand_vector_addition, expand_vector_operations_1,
	expand_vector_operations, tree_lower_operations,
	pass_lower_vector_ssa, pass_pre_expand): New.
	(expand_complex_operations, pass_lower_complex): Remove.
	* tree-optimize.c (init_tree_optimization_passes): Adjust
	pass ordering for changes in tree-complex.c.
	* tree-pass.h: Declare new passes.
	* tree.c (finish_vector_type): Remove.
	(make_vector_type): New.
	(build_vector_type_for_mode, build_vector_type): Rewritten.
	* tree.def (VECTOR_TYPE): Document where the number of
	subparts is stored.
	* tree.h (TYPE_VECTOR_SUBPARTS): Use TYPE_PRECISION field.
	(make_vector): Remove declaration.
