PTX compilation failed with bytes

[samy2]

Hi,
I tested today the master branch (commit cf83683).
All the bugs I reported are corrected (great work!), except this one :

    [Test]
    public void CompilationTest3()
    {
        using (var context = new Context())
        {
            using (var gpu = new CudaAccelerator(context, 0))
            {
                var method = GetType().GetMethod(nameof(Kernel3), BindingFlags.NonPublic | BindingFlags.Static);
                var compiledKernel = gpu.Backend.Compile(method, KernelSpecialization.Empty);
                var loadedKernel = gpu.LoadKernel(compiledKernel);
                loadedKernel.Dispose();
            }
        }
    }

    private static void Kernel3(GroupedIndex index, ArrayView<float> array)
    {
        byte b = 1;
        for (int i = 0; i < 2; i++)
        {
            if (b > 1)
            {
                array[0] = 1;
            }
            b = 2;
        }
    }

The exception I get : ILGPU.Runtime.Cuda.CudaException : 'a PTX JIT compilation failed'

It turns out that the PTX backend still generates some invalid movement instructions (in this case for temporary registers). The problem will be fixed in the next commit.

BTW you can also use

using ILGPU.Runtime;
...
var kernel = gpu.LoadKernel<GroupedIndex, ArrayView<float>>(Kernel3);

to load your kernel. However, you cannot inspect the generated PTX code in this case.

I confirm that it works with the last commit! Great!
