With x86_64, ciphers like aes-128-cbc are much faster with
AES-NI, so a simple benchmark:

openssl speed aes-128-cbc
openssl speed -evp aes-128-cbc

will tell you if the code uses hardware acceleration, as it's
only the EVP that is accelerated.

But when I've tested it on AArch64 with openssl-1.1.0-pre5
and current master
(./configure no-shared no-engine)
I'm getting 100524.03k vs 52172.12k/s in favour of the non-EVP
version.

Is that really expected?

With 1.0.1 and 1.0.2 I'm getting around 100000k/s with and without
EVP, so that looks like a regression to me.
