Hi Aditya,

I uploaded the ARM changes here: https://reviews.llvm.org/differential/diff/118037/

As a sidenote, this caused trouble with some of my integration tests because now the legalize combiner finds all sorts of opportunities to replace trunc + ext with shifts, which weren't implemented on ARM yet (they are now). I don't think the combiner should be introducing instructions without first checking if they are legal, maybe you can consider fixing that in the future.
