bytes.IndexByte is heavily optimized. Use it in findnull. This is second attempt, similar to CL97523. In this version we never call IndexByte on region of memory, that crosses page boundary. A bit slower than CL97523, but still fast: name old time/op new time/op delta GoString-6 164ns ± 2% 118ns ± 0% -28.00% (p=0.000 n=10+6) findnull is also used in gostringnocopy, which is used in many hot spots in the runtime.
