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... :-(
