[PATCH] D152059: [AVR] Replace shift-to-loop IR pass with common shift code

[Ben Shi via Phabricator via llvm-commits]

benshi001 added a comment.

I suggest we separate this patch to two ones, one for the 32-bit shift, and another for the subreg liveness. And each one need a clear but brief commit message. We need not mention `aykevl mentioned that they are not currently working on the AVR backend`, just focus on the issue and code is OK enough.
