[x] ROCm `5.7.3` (runtime) + Blender `3.6.15` with `-O3` kernel

Only with kernel compiled with:

```bash
# gfx803
# > https://github.com/xuhuisheng/rocm-gfx803/issues/28
/opt/rocm/bin/hipcc \
    -Wno-parentheses-equality \
    -Wno-unused-value \
    -O3 \
    --amdgpu-target=gfx803 \
    -I /home/rocm/blender/intern/cycles \
    --genco /home/rocm/blender/intern/cycles/kernel/device/hip/kernel.cpp \
    -o kernel_gfx803.fatbin

# Same as:
/usr/bin/hipcc \
    --offload-arch=gfx803 \
    --genco /home/rocm/blender/intern/cycles/kernel/device/hip/kernel.cpp \
    -D CCL_NAMESPACE_BEGIN= \
    -D CCL_NAMESPACE_END= \
    -D HIPCC \
    -I /home/rocm/blender/intern/cycles/kernel/.. \
    -I /home/rocm/blender/intern/cycles/kernel/device/hip \
    -Wno-parentheses-equality \
    -Wno-unused-value \
    -O3 \
    -o kernel_gfx803-O3-original.fatbin
```
