In a "seeing the forest through the trees" kinda situation, I realized that a
...
complete rewrite of load-vn will make it a bit faster. This changes speeds up
the gcse pass (which uses load-vn) from 25.45s to 0.42s on the testcase in
PR209.
I've also verified that this gives the exact same results as the old one.

This is a big diff with no functionality change. We just reorder some code,
...
which causes big reindentation. While I'm at it, I fix the fixme by removing
some dead code.
