OpenCL C version is 1.2 for all targets by default in clang if the version
isn't specified in command line:
https://github.com/llvm/llvm-project/blob/b07c88563febdb62b82daad0480d7b6131bc54d4/clang/lib/Basic/LangStandards.cpp#L99
There is TargetInfo api setSupportedOpenCLOpts for target to define its
supported extensions and features.
