Presumably mucking around with the MEM_EXPR on the DECL isn't going to
mess up inlining? What about debugging?
I'm certain it won't mess up inlining, because all that is long
done with by the time we're in rtl -- it's all just one big

I wouldn't have thought it would mess up debugging, but we'll
have to see what happens with Alex's enhanced var-tracking...
I have attached a patch to pr 37447.
