Add nstream kernel from PRK
...
PRK has a nstream kernel, which is Triad with a += update.
This means there are 3 reads and a write, which is a higher
read/write ratio. In addition, non-temporal stores for the
write on CPUs will not be beneficial, and so compilers should
take care to emit these for the other kernels, but not these.

Allocate driver solution check vectors *after* the main computation
...
Each Stream implementation owns its own data, so the driver code
shouldn't allocate a large array just before. On processors with
strong NUMA effects and smaller memory capacities per NUMA domain,
these checking vectors can result in the main arrays being
allocated in the wrong NUMA domain.
The fix is to simply move the driver allocation until after the
computation has finished and we want to check the answers.
This commit only changes the driver; each model will be updated
in subsequent commits.
Fixes #80 .
