Many of the atomic op implementations are the same except for one instruction; fold the lot into a few CPP macros and reduce LoC. This also prepares for easy addition of new ops. Requires the asm_op because of eor. AVR32 is a bit special in that its ADD/SUB instructions are not symmetric. Its SUB instruction allows for an 21bit immediate.
