	gcc            : ChangeLog tree-ssa-dom.c 

Log message:
	* tree-ssa-dom.c (opt_stats): Move so that it lives just after
	the opt_stats_d structure.
	(vrp_data): Change from a varray into a hash table.
	(vrp_hash_elt): New structure for elements in the vrp hash table.
	(vrp_hash, vrp_eq):New functions for hashing and testing equality
	in the vrp hash table.
	(tree_ssa_dominator_optimize): Initialize VRP_DATA.  Reorganize
	initialization slightly to make it easier to read.  No longer need
	to grow/clear the varray.  Instead empty and delete the hash table.
	(dom_opt_finalize_block): Update due to change of VRP_DATA from
	a varray to a hash table.
	(simplify_cond_and_loop_avail_expr, record_range): Similarly.
