You can overload builtins by adding custom type checking to them. The
"templates" in `Builtins.td` is more of a way to generate builtins with the
same pattern for different types. e.g. there are `__builtin_cos`,
`__builtin_cosf` and `__builtin_cosl`, which are essentially identical, except
that they take `double`, `float` and `long double` respectively. To avoid
typing everything out (and making errors that way), you can make the builtin a
template.
