Significant slowdown when running pass 5d (resolve mergeinfo)
On a trial conversion of the gcc repository using the go version of reposurgeon, the resolve mergeinfo pass has jumped from 24s to 7h45 minutes on my machine. This occurred somewhere between commits 86a7f28f and 1ab3c514, but I'll try to narrow it down a bit further.
This is using https://gitlab.com/esr/gcc-conversion.git for the conversion script.
