IFF: decode last 8 pixels per line

The decodeplane8() function processes one byte of input less than

loop.

Switch some ints to unsigned (they can only have positive values, this allows
...
compiler to optimize some math from mul/div to shr/shl). Also add a cast to
uint32_t when calling decodeplane32(), this silences a compiler warning.
Lastly, in decodeplane8/32(), flatten a double-loop into a single-loop and
calculate the length once before entering the loop instead of during every
iteration (since it doesn't change).
