Paul E. Murphy 8614c525b3 crypto/aes: On ppc64le, use better instructions when available 
Several operations emulate instructions available on power9. Use
the GOPPC64_power9 macro provided by the compiler to select the
native instructions if the minimum cpu requirements are met.

Likewise rework the LXSDX_BE to simplify usage when overriding
it. It is only used in one place.

All three configurations are tested via CI.

On POWER9:

pkg:crypto/cipher goos:linux goarch:ppc64le
AESCBCEncrypt1K   949MB/s ± 0%   957MB/s ± 0%  +0.83%
AESCBCDecrypt1K  1.82GB/s ± 0%  1.99GB/s ± 0%  +8.93%
pkg:crypto/aes goos:linux goarch:ppc64le
Encrypt          1.01GB/s ± 0%  1.05GB/s ± 0%  +4.36%
Decrypt           987MB/s ± 0%  1024MB/s ± 0%  +3.77%
