[PATCH] D67645: [aarch64] add def-pats for dot product

[Sebastian Pop via Phabricator via llvm-commits]

sebpop updated this revision to Diff 220501.
sebpop added a comment.

The new patch does not use the first argument of the dot product instruction: we now set it to zero.
Patch tested on x86_64-apple-darwin with `make check-all`.
