Thanks. The callback used in `interp__builtin_ia32_shuffle_generic` only
accepts two parameters,
but in this case we need a callback that takes three parameters.
Maybe `interp__builtin_x86_palignr` should be renamed to
`interp__builtin_ia32_shuffle_generic3`, adding the number 3 to the end of the
name.
