    i386: Add V8QI and other 64bit vector permutations [PR89021]

    In addition to V8QI permutations, several other missing permutations are
    added for 64bit vector modes for TARGET_SSSE3 and TARGET_SSE4_1 targets.

    i386: Add PPERM two-operand 64bit vector permutation [PR89021]

    Add emulation of V8QI PPERM permutations for TARGET_XOP target.  Similar
    to PSHUFB, the permutation is performed with V16QI PPERM instruction,
    where selector is defined in V16QI mode with inactive elements set to 0x80.
    Specific to two operand permutations is the remapping of elements from
    the second operand (e.g. e[8] -> e[16]), as we have to account for the
    inactive elements from the first operand.
