I was able to change a few. For those, I resolved the conversations. The conversations that are still unresolved cause test failures if changed. The reason is that we don't introduce any heuristic yet in this PR to set environment to OpenCL. Therefore some tests that pass triple `spirv[32|64]-unknown-unknown` have environment unknown during the whole execution. We are planning a follow up PR with at least one heuristic to set environment to OpenCL. I think after that one we will be able to change a few more of these, or even all of them. Is that acceptable for you @Keenuts?
