    * doc/invoke.texi: Update -fopt-info documentation.
    * dumpfile.c: Move dump_flags here from passes.c.
    Rename opt_info_options to optinfo_verbosity_options.
    Add optgroup_options.
    (dump_files): Add field for optinfo_flags in the static initializer.
    (dump_register): Handle additional parameter for optgroup_flags.
    (opt_info_enable_passes): Renamed opt_info_enable_all. Handle
    optgroup_flags. Fix documentation.
    (opt_info_switch_p_1): Handle optgroup options.
    (opt_info_switch_p): Handle optgroup_flags. Warn on multiple files.
    * dumpfile.h (dump_register): Additional argument for optgroup_flags.
    All callers updated.
    (struct dump_file_info): Add field for optgroup_flags.
    Define OPTGROUP_* flags.
    * tree-pass.h (struct opt_pass): Add addtional field for optinfo_flags.
    All opt_pass static initializers updated.
    * opts-global.c (dump_remap_tree_vectorizer_verbose): Use 'all'
    instead of 'optall'.
    (handle_common_deferred_options): Fix typo in error message.
    * passes.c (register_one_dump_file): Add argument for optgroup_flags.
    Turn on OPTGROUP_IPA for IPA passes.
    Move dump_flags from here to dumpfile.c.
    * statistics.c (statistics_early_init): Use OPTGROUP_NONE in call to
    dump_register.
