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

Mark the SPU 'lr' instruction to never have side effects. This allows the fast regiser allocator to remove redundant register moves. Update a set of tests that depend on the register allocator to be linear scan. llvm-svn: 106420
