Add SM4 ARMv8/AArch64/CE assembly implementation
* cipher/Makefile.am: Add 'sm4-armv8-aarch64-ce.S'.
* cipher/sm4-armv8-aarch64-ce.S: New.
* cipher/sm4.c (USE_ARM_CE): New.
(SM4_context) [USE_ARM_CE]: Add 'use_arm_ce'.
[USE_ARM_CE] (_gcry_sm4_armv8_ce_expand_key)
(_gcry_sm4_armv8_ce_crypt, _gcry_sm4_armv8_ce_ctr_enc)
(_gcry_sm4_armv8_ce_cbc_dec, _gcry_sm4_armv8_ce_cfb_dec)
(_gcry_sm4_armv8_ce_crypt_blk1_8, sm4_armv8_ce_crypt_blk1_8): New.
(sm4_expand_key) [USE_ARM_CE]: Use ARMv8/AArch64/CE key setup.
(sm4_setkey): Enable ARMv8/AArch64/CE if supported by HW.
(sm4_encrypt) [USE_ARM_CE]: Use SM4 CE encryption.
(sm4_decrypt) [USE_ARM_CE]: Use SM4 CE decryption.
(_gcry_sm4_ctr_enc, _gcry_sm4_cbc_dec, _gcry_sm4_cfb_dec)
(_gcry_sm4_ocb_crypt, _gcry_sm4_ocb_auth) [USE_ARM_CE]: Add
ARMv8/AArch64/CE bulk functions.
* configure.ac: Add 'sm4-armv8-aarch64-ce.lo'.
--
This patch adds ARMv8/AArch64/CE bulk encryption/decryption. Bulk
functions process eight blocks in parallel.
