Having a function per each supported size plus one for emulated locking is still safer than having a pair, where one deals with opaque data type.

It is visible.

https://llvm.org/docs/Atomics.html ("libcalls" section)

Having a clear and reasonable error messages is reasonable as well. This is easier to implement it at compiler site.
