    * tree.h (tree_optimization_option): Rename target_optabs to optabs.
    Add base_optabs.
    (TREE_OPTIMIZATION_OPTABS): Update after previous field change.
    (TREE_OPTIMIZATION_BASE_OPTABS): New macro.
    (save_optabs_if_changed): Replace with...
    (init_tree_optimization_optabs): ...this.
    * optabs.c (save_optabs_if_changed): Rename to...
    (init_tree_optimization_optabs): ...this.  Take the optimization node
    as argument.  Do nothing if the base optabs are already correct.
    Reuse the existing TREE_OPTIMIZATION_OPTABS memory if we need
    to recompute optabs.
    * function.h (function): Remove optabs field.
    * function.c (invoke_set_current_function_hook): Call
    init_tree_optimization_optabs.  Use the result to initialize
    this_fn_optabs.
