Bug fix for PR1279. When isDead is propagate by copy coalescing, we keep length of dead def live interval at 1 to avoid multiple def's targeting the same register. The previous patch missed a case where the source operand is live-in. In that case, remove the whole interval. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35512 91177308-0d34-0410-b5e6-96231b3b80d8
