Compile-time numbers look good: http://llvm-compile-time-tracker.com/compare.php?from=f52e0507574b4fd84dc4674536f5dfbab396c0f6&to=0a009b654793dee8e335c053eb043e297071e0d1&stat=instructions
Change does not seem to have cost above noise, apart from a -0.6% improvement on tramp3d-v4. There's a corresponding -0.74% reducing in code-size, so this transform is clearly doing (or enabling) something big there. It might be interesting (but not necessary) to take a quick look at what happens there.
