Re: [PATCH] Improve cost computations in IVOPTS


> OK (with the changes proposed by Richard), and

I cannot use STRIP_USELESS_TYPE_CONVERSION instead of STRIP_NOPS though 
because I need to strip the conversions from POINTER_TYPE to INTEGER_TYPE 
added earlier during creation of IVs.  But I'll use cst_and_fits_in_hwi.

OK, I'm going to conduct some experiments in this area.
