bors f39ba69aaa auto merge of #13539 : Aatch/rust/vector-copy-faster, r=thestinger

LLVM wasn't recognising the loops as memcpy loops and was therefore failing to optimise them properly. While improving LLVM is the "proper" way to fix this, I think that these cases are important enough to warrant a little low-level optimisation.

Fixes #13472
