    [PATCH] Call flush_ssaname_freelist more often
           * passes.c (execute_function_todo): Do not call
flush_ssaname_freelist
            here.  Instead...
            (execute_todo): Call it here.
            * tree-ssanames.c (make_ssa_name_fn): Unconditionally gather reuse
            statistics
            (pass_release_ssa_names::execute): Do not call
flusH_ssaname_freelist.
