@pogo59, it looks like it's possible to overload builtins using templates in
`clang/Basic/Builtins.td` as you said (for example, see `SyncFetchAndAddN`).
However,
1. `char8_t` for builtin types isn't currently supported. We'll need to fix a
few places in clang including tablegen to support that type.
2. It seems that the overloaded builtin will need a suffix (e.g., `_u8`) to
distinguish it from the original one.
I think we can try to add support for that in a follow up patch unless it's
something we need now.
