Fix assertion in jump threading (PR13405). GetBestDestForJumpOnUndef() assumes there is at least 1 successor, which isn't true if the block ends in an indirect branch with no successors. Fix this by bailing out earlier in this case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160546 91177308-0d34-0410-b5e6-96231b3b80d8 2012-07-20 10:36:17 +00:00			`; RUN: opt < %s -jump-threading`
