Add SM4 x86-64/AES-NI/AVX2 implementation
* cipher/Makefile.am: Add 'sm4-aesni-avx2-amd64.S'.
* cipher/sm4-aesni-avx2-amd64.S: New.
* cipher/sm4.c (USE_AESNI_AVX2): New.
(SM4_context) [USE_AESNI_AVX2]: Add 'use_aesni_avx2'.
[USE_AESNI_AVX2] (_gcry_sm4_aesni_avx2_ctr_enc)
(_gcry_sm4_aesni_avx2_cbc_dec, _gcry_sm4_aesni_avx2_cfb_dec)
(_gcry_sm4_aesni_avx2_ocb_enc, _gcry_sm4_aesni_avx2_ocb_dec)
(_gcry_sm4_aesni_avx_ocb_auth): New.
(sm4_setkey): Enable AES-NI/AVX2 if supported by HW.
(_gcry_sm4_ctr_enc, _gcry_sm4_cbc_dec, _gcry_sm4_cfb_dec)
(_gcry_sm4_ocb_crypt, _gcry_sm4_ocb_auth) [USE_AESNI_AVX2]: Add
AES-NI/AVX2 bulk functions.
* configure.ac: Add ''sm4-aesni-avx2-amd64.lo'.

This patch adds x86-64/AES-NI/AVX2 bulk encryption/decryption. Bulk
functions process 16 blocks in parallel.
