I see we would have to do an abstract interpretation of a DIExpression together with the implicit register operand bound by the DBG_VALUE to computes all stack slots that my be touched by the expression, assuming we even know where non-frame-pointer registers point. Could you add an explanation to the comment that lays out why this isn't feasible?
