clang-p2996/llvm/test/CodeGen/X86/stack-folding-adx.mir
Craig Topper 02b614abc8 [X86] Merge addcarryx/addcarry intrinsic into a single addcarry intrinsic. 
Both intrinsics do the exact same thing so we really only need one.

Earlier in the 8.0 cycle we changed the signature of this intrinsic without renaming it. But it looks difficult to get the autoupgrade code to allow me to merge the intrinsics and change the signature at the same time. So I've renamed the intrinsic slightly for the new merged intrinsic. I'm skipping autoupgrading from the previous new to 8.0 signature. I've also renamed the subborrow for consistency.
