SYCL-CTS test_vector_swizzles doesn't compile for NVPTX target.

[bader]

Describe the bug
I'm building SYCL-CTS using DPC++ with NVPTX target support and building of the test_vector_swizzles fails with following error:

ptxas fatal   : Unresolved extern function '_Z18__spirv_AtomicIAddPyN5__spv5Scope4FlagENS0_19MemorySemanticsMask4FlagEy'

NOTE: Might be related to #5647 and #5215.

To Reproduce
Please describe the steps to reproduce the behavior:

git clone --recurse-submodules https://github.com/KhronosGroup/SYCL-CTS.git
cd SYCL-CTS
cmake -S . -B build -DSYCL_IMPLEMENTATION=DPCPP -DSYCL_CTS_EXCLUDE_TEST_CATEGORIES=ci/dpcpp.filter -DSYCL_CTS_ENABLE_DOUBLE_TESTS=OFF -DSYCL_CTS_ENABLE_HALF_TESTS=OFF -DSYCL_CTS_ENABLE_DEPRECATED_FEATURES_TESTS=OFF -DSYCL_CTS_ENABLE_OPENCL_INTEROP_TESTS=OFF -DDPCPP_INSTALL_DIR=<compiler-install-dir> -DDPCPP_TARGET_TRIPLES=nvptx64-nvidia-cuda
cmake --build ./build

I see that this issue also impacts test_optional_kernel_features.

[bader]

The test passes on the same machine with DPC++ built from bfc7e98.

test_optional_kernel_features still fails.

[bader]

@AerialMantis, if you won't be able to reproduce this problem with the recent DPC++, please, close the ticket.

[bader]

That's very strange as I haven't updated CUDA version, so my theory is that patches from llvm.org and spir-v translator remove uses of atomic add instructions.

[AerialMantis]

Thanks @bader, that's interesting, @jchlanda has just picked up this task, so he will be looking into it, if we're not able to reproduce it, we'll consider it resolved as you suggest.

[jchlanda]

I've just checked with the top of llvm/sycl f963 and top of CTS da7b and the swizzle tests build just fine.

[bader]

@jchlanda, are you able to build test_optional_kernel_features?

[jchlanda]

Huh, so test_optional_kernel_features fails with the same missing symbol, I'll re-open the ticket.
