gtensor_unravel_reproducer

Reproduce bug seen with ROCm 5.2.0, -O2, and per dim kernels off (default). On machine with ROCm installed and supported gpu, run like this:

export ROCM_PATH=/opt/rocm
export HIP_GPU_ARCHITECTURES=gfx803,gfx906,gfx908,gfx90a:xnack+,gfx1030
./run-unravel-reproducer.sh

Tested and reproduced with gfx1030 and gfx90a:xnack+.
