[PATCH] D159190: [RISCV]Combine to make the fixed vector vadd of splats are scalarized

[Luke Lau via Phabricator via llvm-commits]

Thanks for the patch. Did you take a look at scalarizeBinOpOfSplats in DAGCombiner? I think that might be more generic, it's the combine that kicks in for the scalable vector test case in that issue. I was wondering if it would be possible to get it to work on fixed vectors too.
