[Intrinsics] Added writeonly attribute to the first arg of llvm.memmove
D18714 introduced writeonly attribute:
"Also start using the attribute for memset, memcpy, and memmove intrinsics,
and remove their special-casing in BasicAliasAnalysis."
But actually, writeonly was not attached to memmove - oversight, it seems.
So let's add it. As we can see, this helps DSE to eliminate redundant stores.
