Log message:
	2004-11-19  Andrew Pinski  <pinskia@physics.uc.edu>
	
	PR tree-opt/18507
	* tree-flow.h (tree2): Typedef because there is already a VEC(tree).
	Define a VEC(tree2) for head.
	(register_new_def): Change second argument to be a VEC(tree2).
	* tree-ssa-dom.c (block_defs_stack): Change to be a VEC(tree2).
	(tree_ssa_dominator_optimize): Initialize block_defs_stack with
	the VEC(tree2) function.  Also free it before returning.
	(dom_opt_initialize_block): Use VEC_safe_push instead of VARRAY_PUSH_TREE
	for block_defs_stack.
	(restore_currdefs_to_original_value): Use VEC_length instead of
	VARRAY_ACTIVE_SIZE. VEC_pop instead of VARRAY_TOP_TREE/VARRAY_POP.
	(dom_opt_finalize_block): Use VEC_safe_push instead of VARRAY_PUSH_TREE
	for block_defs_stack.
	* tree-into-ssa.c (block_defs_stack): Change to be a VEC(tree2).
	(rewrite_initialize_block): Use VEC_safe_push instead of VARRAY_PUSH_TREE
	for block_defs_stack.
	(ssa_register_new_def): Likewise.
	(ssa_rewrite_initialize_block): Likewise.
	(rewrite_finalize_block): Use VEC_length instead of
	VARRAY_ACTIVE_SIZE. VEC_pop instead of VARRAY_TOP_TREE/VARRAY_POP.
	(ssa_rewrite_finalize_block): Likewise.
	(register_new_def): Change second argument to be a VEC(tree2).
	Use VEC_safe_push instead of VARRAY_PUSH_TREE.
	(rewrite_blocks): Initialize block_defs_stack with
	the VEC(tree2) function.  Also free it before returning.
	(rewrite_ssa_into_ssa): Likewise.
