Patch that hopefully fixes the problem for good
Here's a patch that fixes the latent problem that caused us to issue MOps that
bound parts of multi-part variables to MEMs whose addresses refer to
debug_exprs. We shouldn't do that, for we have no infrastructure to recompute
the location of the multi-part variable as the debug_expr changes, and we
shouldn't have to: VT tracks locations (REGs or MEMs), rather than values, and
the locations aren't supposed to change.
