In the adler32_neon function, during the last iteration of the
loop through "accum32_neon", we would load data after the end of the
buffer (in the ld1 instruction, the "start" register points to the end
of the buffer).
If this memory is unmapped, this would cause a segfault. If the memory
is mapped, the checksum would be correct because that value would
only be used in the next iteration, but this happens during the last
iteration.
To fix this, we can simply do the load before incrementing "start". And
while we're at it, we can load directly into d0_v/d1_v, saving a couple
of mov's.
Finally, the ld1 done during the function initialization can be removed
as the values aren't used for anything.
