libbacktrace returns the line number that you actually care about: the line

There's not enough information in those comments to definitively say the SEME
copier isn't updating the SSA graph properly. If I were looking at this, I'd
want the dump as we enter VRP

I added a pass of update_ssa after each invocation of the SEME copier, and that
produced 26 extra fails (on top of the failing test) in the hmmer make check.

But you can need updates that extend beyond the scope of the SEME I would

From a sequencing standpoint, you do your block copying wire up the new
