[BUG] BINOP_DIV and ptyp command

I don't think this is right. EVAL_AVOID_SIDE_EFFECTS is used when
computing the actual value is not needed. For instance, when you do
"ptype", the expression is evaluated in that mode.  So when you do
"ptype 3 div 2", we don't do the division, we just know that we're only
interested in the type of result.  So the expression evaluator will
return a struct value of the correct type but with a bogus contents,
instead of doing the division, only to discard the result down the road.

So the code you suggested we remove is useful.
