Makefile.in (tree-ssanames.o): Depend on TREE_FLOW_H.
* Makefile.in (tree-ssanames.o): Depend on TREE_FLOW_H.
* tree-flow.h (ssa_names, num_ssa_names, ssa_name): Declare.
(highest_ssa_version): Remove.
* tree-outof-ssa.c (new_temp_expr_table): Replace
highest_ssa_version with num_ssa_names.
(dump_replaceable_exprs): Likewise.
(rewrite_vars_out_of_ssa): Likewise.
* tree-ssa-ccp.c (initialize): Likewise
* tree-ssa-copyrename.c (rename_ssa_copies): Likewise.

* tree-ssa-live.c (create_ssa_var_map): Likewise.
(dump_var_map): Likewise.
* tree-ssa.c (verify_ssa): Likewise.
(kill_redundant_phi_nodes): Likewise.
Do not build a local array of SSA_NAMEs. Use the ssa_names table.
* tree-ssanames.c: Include tree-flow.h
(ssa_names): New varray.
(init_ssa_names): Initialize ssa_names.
Reserve the first slot of the ssa_names table.
(make_ssa_name): Push the newly created SSA_NAME into ssa_names.
Assign version numbers using num_ssa_names.
