At the tex level you need either

   \lccode`\'=`\'

or make the ' an active character running a macro that is a bit like
||, e.g. this:

   \catcode`\'=\active
   \unexpanded\def'{\string'\prewordbreak}

With the second solution, you have to be careful with your input
(active characters are always dangerout in the regard) but the
first solution has the downside that it decreases the \lefthyphenmin
by two:  d'ins-truc-cions then is a single word with 5-4-5 charachers
in it, and that may change hyphenation into e.g. d'i-ns-truc-cions.
Whether that is a problem depends on your actual language.


Best wishes,
Taco
