Turns out we do have saturated arithmetic in mfbt, I just missed it.
Also, use just an uint32 for the heuristic. Text length is a uint32 anyway, and
it's unlikely we want to decide anything when the value is over the max uint32
value.

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..
