Right now the only thing we are doing here is pulling in the OpenMP device RTL, but in the future I expect the final version of Intel's OpenMP support to have somewhat complicated logic here pulling in various things, so I think it makes sense to have a new toolchain for now to not bog down the generic SPIR-V toolchain.
