There are many planes whose controls (roll or pitch or both) stiffen up significantly at higher combat speeds: P-38's, Zeros, A-20's, Bf 109's, Bf 110's, TBM's, most bombers, etc. I've seen historical information for at least some of these that talks about this happening.
There are planes that come apart if dive speed is too high: Ki-84's, Mosquitoes, Zeros, most bombers, etc. I haven't read enough on these to know if there's much out there that talks about them coming apart at high speeds and thus have no opinion on it.
