[PATCH] D18028: DAGCombiner: Relax alignment restriction when changing store type

[Tim Northover via llvm-commits]

I think the ARM change is probably fine. There's real ARM code designed to transform a VMOVDRR/VSTR into two STRs (for legitimate, if debatable reasons: vmov was really slow on some cores), it just doesn't happen to trigger if the type is a vector.
