* cipher/sm4-aarch64.S: New.
* cipher/sm4.c (USE_AARCH64_SIMD): New.
(SM4_context) [USE_AARCH64_SIMD]: Add 'use_aarch64_simd'.
[USE_AARCH64_SIMD] (_gcry_sm4_aarch64_crypt)
(_gcry_sm4_aarch64_ctr_enc, _gcry_sm4_aarch64_cbc_dec)
(_gcry_sm4_aarch64_cfb_dec, _gcry_sm4_aarch64_crypt_blk1_8)
(sm4_aarch64_crypt_blk1_8): New.
(sm4_setkey): Enable ARMv8/AArch64 if supported by HW.

(_gcry_sm4_ocb_crypt, _gcry_sm4_ocb_auth) [USE_AARCH64_SIMD]:
Add ARMv8/AArch64 bulk functions.
* configure.ac: Add 'sm4-aarch64.lo'.
--
This patch adds ARMv8/AArch64 bulk encryption/decryption. Bulk
functions process eight blocks in parallel.
