Teach SimplifyCFG how to simplify indirectbr instructions. - Eliminate redundant successors. - Convert an indirectbr with one successor into a direct branch. Also, generalize SimplifyCFG to be able to be run on a function entry block. It knows quite a few simplifications which are applicable to the entry block, and it only needs a few checks to avoid trouble with the entry block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111060 91177308-0d34-0410-b5e6-96231b3b80d8
