	checking whether AnalyzeBranch disagrees with the CFG directly, rather than looking for EH_LABEL instructions. EH_LABEL instructions aren't always at the end of the block, due to FP_REG_KILL and other things. This fixes an infinite loop compiling MultiSource/Benchmarks/Bullet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96611 91177308-0d34-0410-b5e6-96231b3b80d8
