Roll r127459 back in: 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>. llvm-svn: 127498

Run codegen dce pass for all targets at all optimization levels. Previously it's only run for x86 with fastisel. I've found it being very effective in eliminating some obvious dead code as result of formal parameter lowering especially when tail call optimization eliminated the need for some of the loads from fixed frame objects. It also shrinks a number of the tests. A couple of tests no longer make sense and are now eliminated. llvm-svn: 95493
