[PATCH] D138529: [AVR] Optimize constant 32-bit shifts

[Ben Shi via Phabricator via llvm-commits]

Is it possible to break this large patch to smaller ones, in which the first one is just the skeleton (with only shiftAmount = 1 implemented as the basic situation) ? Then later ones implment each special shiftAmount  case .
