Same as all the other atomics: run screaming for the hills (or error out, in more reasonable terms). The only way to implement floating atomics in LLVM IR would be with a compare-exchange loop and Clang doesn't expose anything to make that more convenient. Min/max have at least some pedigree in integer terms. OpenCL has specified them, CPUs have implemented them, and we've had requests for builtins from users.
