haha nope. This is not a part of AES-NI.

The only processors so far with these extensions are low power Goldmont chips.

Goldmont probably has them because it doesn't have the wide AVX pipelines necessary for fast software crypto.

Skylake can compute SHA1 at 4.3-3.4 cycles/B and SHA256 at 7-9 cycles/B [1]. That's ~1GB/s SHA1 and ~500MB/s SHA256.
