SHA512: Add AVX512 implementation
* LICENSES: Add 'cipher/sha512-avx512-amd64.S'.
* cipher/Makefile.am: Add 'sha512-avx512-amd64.S'.
* cipher/sha512-avx512-amd64.S: New.
* cipher/sha512.c (USE_AVX512): New.
(do_sha512_transform_amd64_ssse3, do_sha512_transform_amd64_avx)
(do_sha512_transform_amd64_avx2): Add ASM_EXTRA_STACK to return value
only if assembly routine returned non-zero value.
[USE_AVX512] (_gcry_sha512_transform_amd64_avx512)
(do_sha512_transform_amd64_avx512): New.
(sha512_init_common) [USE_AVX512]: Use AVX512 implementation if HW
feature supported.
