* buildsym.c (finish_block): If finishing a function without known
parameter type info, set that from parameter symbols.
* c-typeprint.c (c_type_print_varspec_suffix): For TYPE_CODE_FUNC,
print parameter types, if available.
* ch-typeprint.c (chill_type_print_base): Likewise.
* gdbtypes.h (struct type): Remove function type field.
(TYPE_FUNCTION_TYPE): Remove macro. We can't as simply re-use
function types now that we're also storing parameter types.
And the payoff is much less.
* gdbtypes.c (make_function_type): Don't use/set TYPE_FUNCTION_TYPE.
(recursive_dump_type): Don't print TYPE_FUNCTION_TYPE.
* dwarfread.c (read_subroutine_type): Don't set TYPE_FUNCTION_TYPE.
