type llpassbuilder_options

(** [run_passes m passes tm opts] runs a set of passes over a module. The
    format of the string [passes] is the same as opt's -passes argument for
    the new pass manager. Individual passes may be specified, separated by
    commas. Full pipelines may also be invoked. See [LLVMRunPasses]. *)
