The addcarry and addcarryx builtins do the same thing. The only difference is that addcarryx previously required adx feature. This commit removes the adx feature check from addcarryx and removes the addcarry builtin. This matches the builtins that gcc has. We don't guarantee compatibility in builtins, but we generally try to be consistent if its not a burden. llvm-svn: 348738
