> From all the above arguments, I feel like the right approach would be to implement it as Clang builtin which closely matches the operator semantic in my opinion. We could of course reuse the implementation of __bultin_astype to avoid unnecessary extra work and code duplication.

I don't think we need another Clang built-in. __builtin_astype was added specifically for OpenCL needs (see rev. 132612).
Do you know better way to map astype operators (there are a lot of them as_<type>#) to single Clang built-in?
