Aurelien Jarno 65cf1f65be target-ppc: fix vcipher, vcipherlast, vncipherlast and vpermxor
For vector instructions, the helpers get pointers to the vector register
in arguments. Some operands might point to the same register, including
the operand holding the result.

When emulating instructions which access the vector elements in a
non-linear way, we need to store the result in an temporary variable.

This fixes openssl when emulating a POWER8 CPU.

Specifically:

      AES_t[ed][0-4] tables.
    - vncipher is recoded to use a combination of InvS-Box, InvShiftRows and
      InvMixColumns tables.  It was not possible to use AES_Td[0-4] due to a

    mask = (1 << (3 + log2(sizeof(element)))) - 1

but what is implemented is:

    mask = (1 << (3 + (sizeof(element)/2))) - 1

This produces correct answers when "element" is uint8_t, uint16_t or uint_32t.  But
it breaks down when element is uint64_t.

This patch corrects the situation.  Since the mask is known at compile time, the
macros are changed to simply accept the mask as an argument.

Subsequent patches in this series will add double-word variants of rotates and
shifts and thus take advantage of this fix.
