## Detailed Description

Defines an IRPrinter that emits C++ code that:

1. wraps PyTorch's C++ tensor into Halide * buffers,
2. calls the corresponding Halide operator.
3. maps the output buffer back to a PyTorch tensor.

The generated code checks for runtime errors and raises PyTorch exception accordingly. It also makes sure the GPU device and stream are consistent when the PyTorch input, when applicable.
