Speedup str[a:b] and PyUnicode_FromKindAndData
* str[a:b] doesn't scan the string for the maximum character if the string
is ascii only
* PyUnicode_FromKindAndData() stops if we are sure that we cannot use a
shorter character type. For example, _PyUnicode_FromUCS1() stops if we
have at least one character in range U+0080-U+00FF
