[ValueTracking] Remove deadish code from computeKnownBitsAddSub. The code assigned to KnownZero, but later code unconditionally assigned over it. I'm pretty sure the later code can handle the same cases and more equally well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@298190 91177308-0d34-0410-b5e6-96231b3b80d8
