[OpenCL] all but one of the example applications fail (cannot find elementselectW16 kernel or decoder_output_concat1 operation not supported)

With pocl:

$ POCL_DEBUG=1 bin/mnist -platform=0 -device=0 -opencl
Loading the mnist database.

Tested also with the Intel's CPU driver:

Thanks for reporting it! Looks like an oversight.

We need to add the missing variants of this kernel similar to how we do it for e.g. elementcmplte kernel.

Actually seems all but ptb fail with OpenCL. cifar10 fails with the same missing kernel.

The other error I get for char-rnn and fr2en is

../lib/ExecutionEngine/ExecutionEngine.cpp:260: void glow::ExecutionEngine::compile(glow::Function *, const glow::CompilationContext &, bool): Assertion `backend_->isOpSupported(N) && "Backend must support all nodes after high-level optimizations."' failed.

@SplitInfinity This is fixed now, right?

For mnist and cifar10 yes, but not for char-rnn and fr2en. I think those fail with a different error.
