Fixing incorrect bitshifting instructions on PowerPC architectures. The program expects simdi_shiftx to shift by bytes while vec_slx shifts the whole vector by bits. vec_sxo is used instead, as far as I know the least significant 3 bits are ignored so the input must be shifted. simdi32_sxli is expected to shift within 32 bit lanes but vec slx shifts the whole vector. vec_sx is used instead with an unsigned integer argument.
