Log message:
	2003-12-16  Andrew MacLeod  <amacleod@redhat.com>
	
	* tree-flow-inline.h (free_vuse, free_vdefs): Moved to
	tree-ssa-operands.c
	(get_def_ops, get_use_ops, get_vdef_ops, get_vuse_ops): Use the new
	more direct structure pointer.
	(get_use_op_ptr, get_def_op_ptr): Cast is no longer necessary.
	* tree-flow.h (struct stmt_ann_d): Replace operands and voperands
	pointers with pointers directly to the operand types.
	* tree-ssa-dom.c (cprop_into_stmt): Use new stmt based interface to
	free virtual operands.  Check virtual bases of both VUSE and VDEF.
	* tree-ssa-operands.c (struct voperands_d): Declare here, used only
	for previous_vops during stmt operand construction.
	(struct vecmanage_d, vecmanage_add_segmen, vecmanage_add_special,
	vecmanage_init, vecmanage_tree_ptr_init, vecmanage_fini, check_free,
	vecmanage_new_vector, vecmanage_new_tree_ptr_vector,
	vecmanage_free_vector): Remove.
	(allocate_ssa_op_vec, free_ssa_op_vec, allocate_ssa_virtual_op_vec,
	allocate_operands_t, allocate_voperands_t): Remove.
	(finalize_new_ssa_operands, inalize_new_ssa_virtual_operand): Remove.
	(struct freelist_d): New. List of free operand structures.
	(check_optype_freelist): New. Choose memory from freelist, if available.
	(add_optype_freelist): New. Add structure to freelist, if appropriate.
	(allocate_def_optype): New. Allocate a def operand list from GC.
	(allocate_use_optype): New. Allocate a useoperand list from GC.
	(allocate_vdef_optype): New. Allocate a vdef operand list from GC.
	(allocate_vuse_optype): New. Allocate a vuse operand list from GC.
	(free_uses, free_defs, free_vuses, free_vdefs): Use GC and the freelist.
	(remove_vuses, remove_vdefs): New.  External interface to remove virtual
	operands.
	(init_ssa_operands, fini_ssa_operands): Ensure the free list is empty.
	(finalize_ssa_defs, finalize_ssa_use, finalize_ssa_vdefs,
	finalize_ssa_vuses): Use new direct pointers from the stmt annotation.
	(append_vdef, append_vuse): No need to hack prev_vops pointer now.
	(get_stmt_operands): use new freeing interface, keep previous vops in
	their own local structure for now, passing its address around.
	* tree-ssa-operands.h (struct def_optype_d, struct use_optype_d,
	struct vdef_optype_d, struct vuse_optype_d): Implement as a single
	dynamically allocated structure.
	(struct operands_d, struct operands_d): Remove.
	* tree-ssa-pre.c (subst_phis): Remove virtual operands using new funcs.
