Avoid segfaults in pos_visible_p

Correct upcasing of ß is normally SS, which is what Fupcase returns if
given a string, or (for special purposes) ẞ.

Recognise ß properly as a lower-case letter (bug#11309)
ß was incorrectly treated as a caseless character and thus not matched
by the regexp [[:lower:]] (or, in case-folding mode, [[:upper:]]).
The reason is that the upcase table maps it to itself, which can be
remedied by mapping it to ẞ (U+7838) instead. Doing so does not
affect upcasing since the special-uppercase property maps it to SS.
* lisp/international/characters.el (tbl): Map ß to ẞ in the upcase
table.
