        * tree-inline.h (struct copy_body_data): Move from tree-inline.c
        and rename from struct inline_data.  Rename callee* to dst*;
        caller* to src*; add copy_decl hook, transform_call_graph_edges,
        transform_new_cfg, transform_return_to_modify, and
        transform_lang_insert_block flags; remove cloning_p, versioning_p,
        update_clones_p.
        (copy_body_r, insert_decl_map, remap_decl, remap_type): Declare.
        (copy_decl_for_dup): Remove.
        * tree-inline.c (struct inline_data): Move to header.
        (insert_decl_map): Export.
        (remap_decl): Update for member name changes.  Use copy_decl hook.
        Allow for replacement to be a non-decl.  Remove dead code.
        (remap_type_1): Check for existing mapping.
        (remap_type): Export.
        (remap_decls): Update for member name changes.
        (remap_block, copy_bb, copy_cfg_body, copy_generic_body): Likewise.
        (copy_body, setup_one_parameter, declare_return_variable): Likewise.
        (expand_call_inline, optimize_inline_calls, clone_body): Likewise.
        (copy_tree_r, mark_local_for_remap_r, unsave_expr_now): Likewise.
        (tree_function_versioning, build_duplicate_type): Likewise.
        (copy_body_r): Likewise.  Export.
        (copy_decl_for_dup): Split into ...
        (copy_decl_for_dup_finish, copy_decl_to_var,
