You may find some useful informations in /var/log/emerge.log : all lines
containing ":::" show a succesful emerge.

If you have kept the contents of this file since you installed your system,
you could then get the list of all packages you have installed. It would be
a start that you could cleanup afterwards. However, this will include system
packages and dependencies. And if you have uninstalled many packages (as
with any update), they would also still be present in that list.
