atomics/treewide: Make unconditional inc/dec ops optional
Many of the inc/dec ops are mandatory, but for most architectures inc/dec are
simply trivial wrappers around their corresponding add/sub ops.
Let's make all the inc/dec ops optional, so that we can get rid of these
boilerplate wrappers.
The instrumented atomics are updated accordingly.
There should be no functional change as a result of this patch.
