intel-xpu-backend-for-triton

Translate a Triton kernel from the deprecated block-pointer API (tl.make_block_ptr / tl.advance / tl.load(boundary_check=...)) into an equivalent kernel using the modern device-side tensor-descriptor API (tl.make_tensor_descriptor / desc.load / desc.store) for the Intel XPU backend. Use this skill whenever the user wants to migrate, convert, translate, port, modernize, or "update" a kernel from block pointers to tensor descriptors; whenever they mention tl.make_block_ptr or tl.advance and ask for a modern/non-deprecated equivalent; whenever they ask how to use tensor descriptors in a kernel that currently uses block pointers; or when they paste a kernel using block pointers and ask how to speed it up or make it use DPAS / 2D block I/O on Intel GPU (PVC/BMG). Produce the descriptor form the XPU backend can lower efficiently, not just any form that compiles.
