add cpu_test_interrupt()/cpu_set_interrupt() helpers and use them tree wide

The helpers form load-acquire/store-release pair and ensure
that appropriate barriers are in place in case checks happen
outside of BQL.

Use them to replace open-coded checkers/setters across the code,
to make sure that barriers are not missed.  Helpers also make code a
bit more readable.
