Hmmmm. I'm not sure people will like this.

I modified tree-chrec under the assumption that *we* (being the scalar 
evolution code) don't care about NON_LVALUE_EXPR.  That isn't to say 
that something else doesn't.
It might have been added to the folder to resolve type casting problems 
or something.
In fact, I think it was (there was a problem related to bool vs int 
types on powerpc that I think that resolved).  I'll take a look at 
tree-ssa and see when the code was added.
But until someone tells us *why* the folder does that, and if it is 
actually necessary, personally, I think we should just modify 
tree-chrec.
