EngineX CI 56fd68e7dd [INFRA] Import NVIDIA/CCCL upstream as optimization reference library
CCCL (CUDA C++ Core Libraries) provides:
- CUB: device/block/warp-level GPU primitives (reduce, scan, sort, topk)
- Thrust: high-level parallel algorithms (transform_reduce, sort, scan)
- libcudacxx: CUDA C++ standard library (atomics, barriers, memory)
- cudax: experimental features (memory resources, allocators)
- Tuning policies: per-SM hardware-specific algorithm parameters

Competition optimization vectors mapped to CCCL:
- Output TPS (83% weight): warp_reduce, block_reduce, device_topk
- Input TPS (14% weight): device_scan, block_load, prefetch
- Cache TPS (3% weight): prefix caching strategy patterns
- Memory (0.9 util): pooled/cached/buddy allocators

/*
* The cuda::ptx namespace intends to provide PTX wrappers for new hardware
* features and new PTX instructions so that they can be experimented with
* before higher-level C++ APIs are designed and developed.
*
* The wrappers have the following responsibilities:
*
* - They must prevent any PTX assembler errors, that is:
* - They are defined only for versions of the CUDA Toolkit in which nvcc/ptxas
* actually recognizes the instruction.
* - Sizes and types of parameters are correct.
* - They must convert state spaces correctly.
* - They adhere to the libcu++ coding standards of using:
* - Reserved identifiers for all parameters, variables. E.g. `__meow` or `_Woof`
* - ::cuda::std:: namespace for types
*
* The wrappers should not do the following:
*
* - Use any non-native types. For example, an mbarrier instruction wrapper
* takes the barrier address as a uint64_t pointer.
*
* This header is intended for:
*
* - internal consumption by higher-level APIs such as cuda::barrier,
* - outside developers who want to experiment with the latest features of the
* hardware.
*
* Stability:
*
* - These headers are intended to present a stable API (not ABI) within one
* major version of the CTK. This means that:
* - All functions are marked inline
* - The type of a function parameter can be changed to be more generic if
* that means that code that called the original version can still be
* compiled.
*
* - Good exposure of the PTX should be high priority. If, at a new major
* version, we face a difficult choice between breaking backward-compatibility
* and an improvement of the PTX exposure, we will tend to the latter option
* more easily than in other parts of libcu++.
*
* Code organization:
*
* - Each instruction is in a separate file and is included below.
* - Some helper function and types can be found in ptx/ptx_helper_functions.h and ptx/ptx_dot_variants.h.
