I don't think this function is worth changing the build configuration to add a dependence of clang::Sema to clang::CodeGen :)

You can just inline (duplicate) the functionality here directly into your function in `AArch64TargetCodeGenInfo::checkFunctionCallABI` and map the attributes directly to the `llvm::AArch64::SMEAttrs` class.

That way you can also avoid needing the `ArmStreamingType` enum.
