    Reland "[dict-proto] SIMD support for SwissNameDictionary in Torque" · 4cd6ad9e
    Igor Sheludko authored
    This is a reland of 856e8577
    The diff compared to the first attempt is that the tests that
    require SSSE3/AVX are not run when these CPU features are not
    available.
    
    Original change's description:
    > [dict-proto] SIMD support for SwissNameDictionary in Torque
    >
    > This CL adds a Torque-counterpart for swiss_table::GroupSse2Impl in
    > Torque. This allows the Torque version of SwissNameDictionary to use
    > SSE for lookups, rather than needing to bailout to the runtime on
    > x64/ia32.
