LOG: [OpenCL][TableGen] Fix type extension guard emission

For certain cases (such as for the double subtype of AGenType), the
OpenCLBuiltinFileEmitterBase would not emit the extension #if-guard.
Fix that by looking at the extension of the actual type instead of the
argument type (which could be a GenType that does not carry any
extension information).
