No. They are not included in any Dist file. 

They are just copied from setjmp.h and bits/setjmp.h (before the VMX 
change) preserving the old setjmp ABI (with some renaming).  I assume we 
don't want the old ABI and structs mixed into the real setjmp.h and 
bits/setjmp.h!

It does have more than strictly necessary for that role. I could combine 
novmsetjmp.h and bits/novmxsetjmp.h and strip anything unnecessary for 
this function?
