New Issue: Should we support convenience operators for methods on atomics

Some methods on atomic variables have direct analogs in Chapel’s operators. For example myAtomic.add(i) feels essentially the same as myAtomic += i. This issue asks whether we could/should support such convenience operators for atomic methods for which it makes sense (ones for which it doesn’t would be things like the CAS-style operators, I expect.
