Add size optimized cipher block copy and xor functions
* cipher/bufhelp.h (buf_get_he32, buf_put_he32, buf_get_he64)
(buf_put_he64): New.
* cipher/cipher-internal.h (cipher_block_cpy, cipher_block_xor)
(cipher_block_xor_1, cipher_block_xor_2dst, cipher_block_xor_n_copy_2)
(cipher_block_xor_n_copy): New.
* cipher/cipher-gcm-intel-pclmul.c
(_gcry_ghash_setup_intel_pclmul): Use assembly for swapping endianness
instead of buf_get_be64 and buf_cpy.
* cipher/blowfish.c: Use new cipher_block_* functions for cipher block
sized buf_cpy/xor* operations.
* cipher/camellia-glue.c: Ditto.
* cipher/cast5.c: Ditto.
* cipher/cipher-aeswrap.c: Ditto.
* cipher/cipher-cbc.c: Ditto.
* cipher/cipher-ccm.c: Ditto.

* cipher/serpent.c: Ditto.
* cipher/twofish.c: Ditto.

This commit adds size-optimized functions for copying and xoring
cipher block sized buffers. These functions also allow GCC to use
inline auto-vectorization for block cipher copying and xoring on
higher optimization levels.
