Auto merge of #5855 - Manishearth:nomove, r=kmc,munksgaard

fixes #5724, #5737


uses https://github.com/Manishearth/rust-tenacious (can be moved in-tree if needed)

I can make it `Deny` by default too (I'll add a cargo feature to tenacious), though we might want it on
`Warn` until we get some mileage on it.
