bpf: Add atomic compare-and-exchange instructions
This patch adds the two remaining BPF v3 atomic instructions:
- BPF_INSN_ACMP{,32}: atomic compare-and-swap
- BPF_INSN_AXCHG{,32}: atomic (non-conditional) exchange
Tests and documentation are also updated.

atomic compare-and-swap instructions.
* testsuite/gas/bpf/atomic.s: Test ACMP, ACMP32, AXCHG, AXCGH32
instructions.
