test/bench: use range in reverse-complement

1.9s	gcc reverse-complement.c

reverse-complement.go
4.5s / 3.5s	original, with/without bounds checks
3.5s / 3.3s	bounds check reduction
3.3s / 2.8s	smarter garbage collector
2.6s / 2.3s	assembler bytes.IndexByte
2.5s / 2.1s	even smarter garbage collector
2.3s / 2.1s	fix optimizer unnecessary spill bug
2.0s / 1.9s	change loop to range (this CL)
