        * tree-ssa.c (maybe_optimize_var): New function split out from ...
        (execute_update_addresses_taken): ... here.
        (non_rewritable_mem_ref_base): Likewise.
        (execute_update_addresses_taken): Do not iterate over all referenced
        vars but just all local decls and parms.
        Properly check call and asm arguments and rewrite call arguments.

        * gcc.c-torture/compile/pr44988.c: Likewise.
