Add SM4 x86-64/AES-NI/AVX implementation
* cipher/Makefile.am: Add 'sm4-aesni-avx-amd64.S'.
* cipher/sm4-aesni-avx-amd64.S: New.
* cipher/sm4.c (USE_AESNI_AVX, ASM_FUNC_ABI): New.
(SM4_context) [USE_AESNI_AVX]: Add 'use_aesni_avx'.
[USE_AESNI_AVX] (_gcry_sm4_aesni_avx_expand_key)
(_gcry_sm4_aesni_avx_crypt_blk1_8, _gcry_sm4_aesni_avx_ctr_enc)
(_gcry_sm4_aesni_avx_cbc_dec, _gcry_sm4_aesni_avx_cfb_dec)

(_gcry_sm4_aesni_avx_ocb_auth, sm4_aesni_avx_crypt_blk1_8): New.
(sm4_expand_key) [USE_AESNI_AVX]: Use AES-NI/AVX key setup.
(sm4_setkey): Enable AES-NI/AVX 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_AVX]: Add
AES-NI/AVX bulk functions.
* configure.ac: Add ''sm4-aesni-avx-amd64.lo'.

This patch adds x86-64/AES-NI/AVX bulk encryption/decryption and key
setup for SM4 cipher. Bulk functions process eight blocks in parallel.
