Fixed up the return types of methods like add() in the internal Atomics.chpl module.
Fixed up the return types of methods like add() in the internal Atomics.chpl module.

[reviewed by Tom]

In Atomics.chpl a bunch of methods like add() claim non-void return types
while not returning anything. A bug future for compiler not reporting
an error is already filed (r22103, r22104).

I specified :void return type explicitly (as opposed to leaving that
implicit, like the write(...) methods do) by Tom's request.
