Subject: [PATCH] De-const the members of QHypotHelper to enable assignment
 operators

Being able to iterate h = h.add(next) over a sequence of numbers makes
it possible to implement arbitrarily-many parameter functions that
need hypot, e.g. the implementation of V4's Math.hypot().
This amends commit b08368d99fa41b3f84cf30468c2dc9f5c2c43423.
