bug#35770: [PATCH] Broken duplicate case elimination in switch byte-compilation

[Mattias Engdegård]

No hurry in reviewing the patch, but since this is a wrong-code bug, I suppose 
it should be back-ported to emacs-26. Does that mean that it should be written 
for that branch and then merged to master, or the other way around?

The test uses bignums for numbers that aren't eq. In Emacs 26, those would be 
floats instead, but bignums seemed more robust since it's not unreasonable to 
have unboxed floats in the future.
