Besides nearby variables, we'd also like to know what is the imminent return
value.  I imagine that's fine for a typical function, and perhaps for inlines
too if optimization didn't morph it away.  But it's not clear to me how DWARF
could help us with the return value from a tail call.  If the callee is
statically known, then perhaps some indirection to that site, but in general I
don't know...
