Preparation for Optimal Edge Profiling:
Optimal edge profiling is only possible when blocks with no predecessors get an virtual edge (BB,0) that counts the execution frequencies of this function-exiting blocks. This patch makes the necessary changes before actually enabling optimal edge profiling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80667 91177308-0d34-0410-b5e6-96231b3b80d8
