These special-purpose arguments and return values are only relevant for the function being compiled, so add a `current` flag to legalize_signature(). - Add the necessary argument values to the entry block to represent the special-purpose arguments. - Propagate the link and sret arguments to return instructions if the legalized signature asks for it.
