All testing passed except validation on Windows with intel/llvm-test-suite#1076 and this Windows portion hangs currently due to machines reconfiguration. :( |

Windows issue is not relevant and same as https://github.com/intel/llvm/runs/7206588798?check_suite_focus=true |

why do we need to be this explicit that this is a constexpr? Is this a performance critical place? Why not just remove constexpr?

I think that all math functions count as performance critical places since they will often be called many many times when used. I think that we could remove constexpr here since at least at O3 there is no difference in the final asm code whether or not constexpr is explicitly used. However I was requested in the review to use c++17 where possible.
Do you want me to remove constexpr usage here?

I'd remove it, but I'll let you to make final call.

OK I've removed it. Thanks

Sorry - I've made further commits to remove some C++17 usage consistent with #6415. if constexpr usage is necessary in joint_matrix_tensorcore.hpp.

Reverts experimental/builtins.hpp includes added in #1072 and #1075. Requires: intel/llvm#6400

Reverts #6386 so that experimental/builtins.hpp is included in sycl.hpp. This avoids users being required to include this header when using printf or experimental math functions.
Corresponding update here: intel/llvm-test-suite#1076.
