[PATCH] D92296: [AARCH64] Improve accumulator forwarding for Cortex-A57 model

[Dave Green via Phabricator via llvm-commits]

> 2. Removed forward from ASMID multiplies (mul, pmul, sqdmulh, smull, umull).

As far as I can tell from some experiments, mul and smull/umull can forward into an accumulator. The others (pmul and sqdmul) do not.  The tests for them would be good to keep too.

Other than that, this looks good to me.
