As Intel is working to add support for SPIR-V OpenMP device offloading in upstream clang/liboffload, we need to modify the OpenMP frontend to allow SPIR-V as well as generate valid IR for SPIR-V. For example, we need the frontend to generate code to define and interact with device globals used in the DeviceRTL. This is the beginning of what I expect will be (many) other changes, but let's get started with something simple. --------- Signed-off-by: Sarnie, Nick <nick.sarnie@intel.com>
