  [CIR] Implement 'simple' atomic inc/dec. (#222730)

This only works for types where a compare-exchange instruction (or just
a lock-free implementation matters) is possible, and a loop isn't
necessary. This is basically just a conversion of classic-codegen,
  except it clarifies some of the logic (particularly around bools).
