[PATCH 3/3] Add SHA-512 implementations for POWER8 and POWER9
* cipher/Makefile.am: Add 'sha512-ppc.c'; Add extra CFLAG handling for
'sha512-ppc.c'.
* cipher/sha512-ppc.c: New.
* cipher/sha512.c (USE_PPC_CRYPTO, _gcry_sha512_transform_ppc8)
(_gcry_sha512_transform_ppc9, do_sha512_transform_ppc8)
(do_sha512_transform_ppc9): New.
(sha512_init_common): Add PowerPC HW feature detection and implemention
selection.
* configure.ac: Add 'vshasigmad' instruction to PowerPC assembly
support check; Add 'sha512-ppc.lo'.

Benchmark on POWER8 ~3.8Ghz:
Before:
| nanosecs/byte mebibytes/sec cycles/byte
SHA512 | 3.47 ns/B 274.6 MiB/s 13.20 c/B

After (~2.08x faster):
| nanosecs/byte mebibytes/sec cycles/byte
SHA512 | 1.66 ns/B 573.1 MiB/s 6.32 c/B

For comparison, OpenSSL 1.1.1b (~1.6% faster):
| nanosecs/byte mebibytes/sec cycles/byte
SHA512 | 1.64 ns/B 582.2 MiB/s 6.22 c/B


Benchmark on POWER9 ~3.8Ghz:
Before:
| nanosecs/byte mebibytes/sec cycles/byte
SHA512 | 2.65 ns/B 359.6 MiB/s 10.08 c/B

After (~1.33x faster):
| nanosecs/byte mebibytes/sec cycles/byte
SHA512 | 1.99 ns/B 479.2 MiB/s 7.56 c/B

For comparison, OpenSSL 1.1.1b (~9.4% faster):
| nanosecs/byte mebibytes/sec cycles/byte
SHA512 | 1.82 ns/B 524.4 MiB/s 6.91 c/B
