Currently, we have support for SYCL 1.2.1 (also known as SYCL 2017). This patch introduces the start of support for SYCL 2020 mode, which is the latest SYCL standard available at (https://www.khronos.org/registry/SYCL/specs/sycl-2020/html/sycl-2020.html). This sets the default SYCL to be 2020 in the driver, and introduces the notion of a "default" version (set to 2020) when cc1 is in SYCL mode but there was no explicit `-sycl-std=` specified on the command line.
