I think it may be problematic if GNU strip reserves -T for other purposes. Can we have a `--strip-*` long option instead? `--strip_swift_symbols` (the obvious option name inferred from the TableGen variable) may not be most suitable because from the description "_$S' or _$s' only if it finds an __objc_image_info section containin" this option only strips some special cased symbols, not all Swift symbols.
