sys-libs/compiler-rt: Provide `atomic-builtins` IUSE flag
Atomic builtins fail to build with GCC. Furthermore, they are not needed
on systems with GCC, because libatomic can be used on them. Atomic
builtins are mostly useful on LLVM-based systems.
Guard them behind the `atomic-builtins` IUSE flag. That flag depends on
`clang`.
