Add Expand-to-libcall support for additional atomics. This covers the usual
entries used by llvm-gcc. *_[U]MIN and such can be added later if needed.
This enables the front ends to simplify handling of the atomic intrinsics by
removing the target-specific decision about which targets can handle the
intrinsics.
