We finally got our buildbot added (to staging, at least) so we want to start running L0 tests in CI. We need `check-offload` to pass though, so XFAIL everything failing. There's a couple `UNSUPPORTED` as well, those are for sporadic fails. Also make set the `gpu` and `intelgpu` LIT variables when testing the `spirv64-intel` triple. We have no DeviceRTL yet so basically everything fails, but we manage to get ``` Total Discovered Tests: 432 Unsupported : 169 (39.12%) Passed : 67 (15.51%) Expectedly Failed: 196 (45.37%) ``` We still don't build the level zero plugin by default and these tests don't run unless the plugin was built, so this has no effect on most builds. --------- Signed-off-by: Nick Sarnie <nick.sarnie@intel.com>
