pick off special one-byte case in copy. worth 2x in benchmarks (38ns->16ns).

gc/runtime: pass type structure to makeslice.
...
* inform garbage collector about memory with no pointers in it
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 (this CL)
