Distilled from Linux XFS source code. foo, inlined into bar, ends
up with debug stmts referencing the addressable variable b.
Optimization made it non-addressable, and then completely optimized
away, before we got a chance to rename (and discard) the occurrence
in the debug stmt. When we did, we crashed, attempting to rename
an unreference variable. */
