Message: Optimize AES-ECB mode in OpenSSL for both aarch64 and aarch32

Aes-ecb mode can be optimized by inverleaving cipher operation on
several blocks and loop unrolling. Interleaving needs one ideal
unrolling factor, here we adopt the same factor with aes-cbc,
which is described as below:
    If blocks number > 5, select 5 blocks as one iteration,every
    loop, decrease the blocks number by 5.
    If 3 < left blocks < 5 select 3 blocks as one iteration, every
    loop, decrease the block number by 3.
    If left blocks < 3, treat them as tail blocks.
Detailed implementation will have a little adjustment for squeezing
code space.
With this way, for small size such as 16 bytes, the performance is
similar as before, but for big size such as 16k bytes, the performance
improves a lot, even reaches to 100%, for some arches such as A57,
the improvement  even exceeds 100%. The following table will list the
encryption performance data on aarch64, take a72 and a57 as examples.
Performance value takes the unit of cycles per byte, takes the format
as comparision of values. List them as below:
