If DoneMBB becomes empty it must have CC added to its live-in list, since it will fall-through into EndMBB. This happens when the CLC loop does the complete range. Review: Ulrich Weigand git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@327834 91177308-0d34-0410-b5e6-96231b3b80d8

; Test memcmp using CLC. In this test case the CLC loop will do all the work

; and the DoneMBB becomes empty. It will not pass the mischeduling verifiers

; if DoneMBB does not have CC in its live-in list.
