[Clang] Only emit CUDA version warnings when creating the CUDA toolchain

This warning primarily applies to users of the CUDA langues as there may
be new features we rely on. The other two users of the toolchain are
OpenMP via `-fopenmp --offload-arch=sm_70` and a cross-compiled build
via `--target=nvptx64-nvida-cuda -march=sm_70`. Both of these do not
rely directly on things that would change significantly between CUDA
versions, and the way they are built can sometims make this warning
print many times.

This patch changees the behaiour to only check for the version when
building for CUDA offloading specifically, the other two will not have
this check.

The LLVM Compiler Infrastructure

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch

Join the LLVM Discourse forums, Discord chat, or #llvm IRC channel on OFTC.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
