This is a catch-all report documenting that we need a proper VRP pass.
Specific PRs can be made dependent on this one, so they can be revisited
once VRP goes in.

Note that a perfectly functioning vrp pass has been on the hammer branch
for years now. It has been rejected at least twice for mainline because
a tree VRP pass was promissed. Sad... :-(
