SYCL Compiler Update Tracking

[rchen20]

Is your feature request related to a problem? Please describe.

The latest SYCL compiler requires C++17, while our TPLs (i.e. BLT benchmark-1.8.0 in particular) are on C++11. Need to search for a SYCL hash which is still compliant with older versions of C++. Alternatively, we need to update everything to be C++17-compliant.

Describe the solution you'd like

Will search for an older SYCL that can support C++11.

Describe alternatives you've considered

Update benchmark-1.8.0 to a newer version (and other TPLs).

Additional context

Issue occurs with new SYCL installation: /usr/workspace/raja-dev/clang_sycl_730cd3a5275f_hip_gcc10.3.1_rocm6.0.2

C++17 support was added in Google benchmark yesterday. I added an issue for BLT to update: LLNL/blt#709.

I think we can go ahead with the SYCL compiler update and use it without enabling Google Benchmark until after a BLT update.
