This reverts commit 6e31857a9db98314b8a748eb024f2c3699ebe2d5, reversing
changes made to 193f4caa8ffa78b4e056893212fd8344aa14e937.
* update clip remove-clip.patch for rebase

* Refactor and add ll128 AR logarithmic factor to tuning models
* Move RCCL tuning changes to a separate file
* Use enum for tunable indexing
* Use explicit indexing in tuning models to avoid mismatch issues
* Place rcclGetSizePerRank in a function
* Remove HIP ifdef for rccl-only call

* Add fault injection of starting warps with random variations
This is done by inserting randomly delays after __syncthreads().
The feature can be turned off by FAULT_INJECTION=OFF in cmake.
* Remove manually introduced bug for demo purpose
* Use only one thread per warp for checking wall clock
COMPILING_TARGETS is not actually used for --offload-arch option,
instead GPU_TARGETS is being used implicitly when we call
find_package(hip REQUIRED) (See hip-config-amd.cmake).
* Accept an EXPLICIT_ROCM_VERSION and use that vs inspecting the environment if provided.
* Use CMake's built in file reading support vs execute_process (without error checking) to avoid silent but deadly later failures.
* Properly quote some comparisons to avoid syntax errors if they happen to have an empty string.
* Guard against ROCM_PATH being an empty string, avoiding stray path extensions to root directories, etc.

* Switched cmake_host_system_information feature to a manual parse to remain cmake 3.5 compliant.
* Updating minimum cmake to 3.16 to conform with the rest of ROCm. This change still applies.
Certain CMake functions deduplicates arguments by default. For example, if we
have two `target_link_options` with both `-Xoffload-linker -opt-A` and then
`-Xoffload-linker -opt-B`, the final link command would be `-Xoffload-linker
-opt-A -opt-B`, which is not what we want.
* Changing C-strings to be const.
* Changed variable-length arrays to std::vector to avoid warnings. VLA is a compiler extension.
* Changed `#define` inside functions into `constexpr int` to preserve scoping and avoid macro redefinition warnings.
* Disabled warnings for modifying `CMAKE_CXX_FLAGS` caused by `check_symbol_exists`, which temporarily modifies the flag to do a compile check.
* Fixed VLA in rccl UT.
* Added restrictions around calling MSCCL++ collectives (#1281)
* Added restriction to non-zero 32-byte multiple message sizes to MSCCL++ AllGather.
* Renamed and refactored some mscclpp types.
* Only transmit the MSCCL++ unique id for non-split comm init. For splitting comm, it has already been transmitted. Instead, save the MSCCL++ communicator in child communicators when calling `ncclCommSplit`. Only destroy MSCCL++ communicators when no RCCL communicators remain that use it. Also improved trace logging.
* Disable MSCCL++ when using managed memory buffers as it isn't supported.
* Added datatype and op constraints for MSCCL++ AllReduce.
* Added documentation on MSCCL++ restrictions to the README.

* Link to libmscclpp_nccl statically (#1282)
* Switched mscclpp_nccl to static linking. Added a build step to rename the NCCL API functions.
* Undid separation of building libmscclpp_nccl from building librccl with MSCCL++ integration. With a static build, it's either fully enabled or fully disabled.
* `nm` isn't always available in docker containers due to being stripped down. Removed use of `nm` in `cmake` and hard-coded the output into mscclpp_nccl_syms.txt.
* Removed IBVerbs dependency for integrating with MSCCL++ (#1313)
* Renamed `RCCL_ENABLE_MSCCLPP` to `RCCL_MSCCLPP_ENABLE` to conform to MSCCL. Set `RCCL_MSCCLPP_ENABLE` to 1 by default if `ENABLE_MSCCLPP` is defined, or 0 otherwise. Added a log warning if `RCCL_MSCCLPP_ENABLE` is set to 1 but `ENABLE_MSCCLPP` is not defined. (#1294)
* Include mscclpp as a git submodule (#1314)
* Added the desired mscclpp commit as a git submodule.
* Added step to automatically checkout the mscclpp submodule if it isn't already present, in case the user forgot to clone recursively.
* Added instruction to README to clone using --recurse-submodules to get the mscclpp submodule.
* Enabled MSCCL++ feature build.
