> With my patch (attached) codecs.utf_16_be_decode runs 5% faster (on 32-bit Linux, I was not tested 64-bit). And of cause no pointers -- no aliasing warnings.

Your patch is wrong: you need to use & 0xffff to get lower 16 bits
when reading a UTF-16 unit. For example, (Py_UCS2)(block >> 32) should
be written (Py_UCS2)((block >> 32) & 0xffff).
