x86: Support for this_cpu_add, sub, dec, inc_return

Supply an implementation for x86 in order to generate more efficient code.

V2->V3:
- Cleanup
- Remove strange type checking from percpu_add_return_op.

tj: - Dropped unused typedef from percpu_add_return_op().
    - Renamed ret__ to paro_ret__ in percpu_add_return_op().
    - Minor indentation adjustments.
