Commit d60a02c8 by Xiong Hu Luo Committed by Xiong Hu Luo
Options

rs6000: Add support for the vec_sbox_be, vec_cipher_be etc. builtins. 

The 5 new builtins vec_sbox_be, vec_cipher_be, vec_cipherlast_be, vec_ncipher_be
and vec_ncipherlast_be only support vector unsigned char type parameters.
Add new instruction crypto_vsbox_<mode> and crypto_<CR_insn>_<mode> to handle
them accordingly, where the new mode CR_vqdi can be expanded to vector unsigned
long long for none _be postfix builtins or vector unsigned char for _be postfix
builtins.
