[PATCH] D75667: [ARM][MVE] Enable *SHRN* for tail predication

[Sam Parker via Phabricator via llvm-commits]

samparker added a comment.

We're allowing instructions which produce a vector and where the output lanes are only dependent upon the same lane on the input register(s). So when I say 'swap', I should say 'exchange'.
