tst_atomic: add atomic_add_return for x86/64, ppc/64 and s390/x In case __sync_add_and_fetch is not provided by compiler, we try to supply our own implementation. It has been taken from kernel 4.5 sources, by compiling a small piece of code (atomic_add_return()) with "gcc -E" and applying some formatting to make it more readable/pretty.
