Most architectures define the atomic/atomic64 xchg and cmpxchg

Add fallbacks for these cases and remove the trivial cases from arch

are used to build other arch_atomic*() operations.

This patch results in:
ERROR: modpost: "__xchg_called_with_bad_pointer" [lib/atomic64_test.ko] undefined!
when trying to build sparc64:allmodconfig.
Guenter, please correct me if I'm wrong:
This is fixed by Arnd's patch "sparc: mark __arch_xchg() as
__always_inline", but that afaics sadly hasn't even reached -next yet.

Hence adding it to the tracking now that the end of the merge window is
near:
#regzbot ^introduced d12157efc8e083c7
#regzbot title locking/atomic: build error on sparc64:allmodconfig
#regzbot ignore-activity
Yes, this is correct.
