Use an anyext to the requested type for the leftover operand to produce a slightly wider type, and then truncate the final merge. I have another implementation almost ready which handles arbitrary widens, but I think it produces worse code in this example (which I think is 90% due to not folding redundant copies or folding out implicit_def users), so I wanted to add this as a baseline first. llvm-svn: 366366
