[objc-arc] Apply the RV optimization to retains next to calls in ObjCARCContract instead of ObjCARCOpts. Turning retains into retainRV calls disrupts the data flow analysis in ObjCARCOpts. Thus we move it as late as we can by moving it into ObjCARCContract. We leave in the conversion from retainRV -> retain in ObjCARCOpt since it enables the dataflow analysis. rdar://10813093 llvm-svn: 180698

Verifier: Call verifyModule() from llc and opt Change `llc` and `opt` to run `verifyModule()`. This ensures that we check the full module before `FunctionPass::doInitialization()` ever gets called (I was getting crashes in `DwarfDebug` instead of verifier failures when testing a WIP patch that checks operands of compile units). In `opt`, also move up debug-info-stripping so that it still runs before verification. There was a fair bit of broken code that was sitting in tree. Interestingly, some were cases of a `select` that referred to itself in `-instcombine` tests (apparently an intermediate result). I split them off to `*-noverify.ll` tests with RUN lines like this: opt < %s -S -disable-verify -instcombine | opt -S | FileCheck %s This avoids verifying the input file (so we can get the broken code into `-instcombine), but still verifies the output with a second call to `opt` (to verify that `-instcombine` will clean it up like it should). llvm-svn: 233432
