3deb9f8eff Generalise the run functions to share construction of models and check vectors 
An enum is added and set by the command line options to choose the running mode:
all 5 kernels or triad only.

There is now only one run fuction which call the constructor of each
model implementation, calling another routine to run the kernels.
The output is then determined by the enum value.

bd04e6db3c 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.
