Optimize trivial branches in CodeGenPrepare, which often get created from the lowering of objectsize intrinsics. Unfortunately, a number of tests were relying on llc not optimizing trivial branches, so I had to add an option to allow them to continue to test what they originally tested. This fixes <rdar://problem/8785296> and <rdar://problem/9112893>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127498 91177308-0d34-0410-b5e6-96231b3b80d8
