If the beginning of the loop was also the entry block of the function, branches were inserted to the entry block which isn't allowed. If this occurs, create a new dummy function entry block that branches to the start of the loop. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195606 91177308-0d34-0410-b5e6-96231b3b80d8
