Further to bug #5686, code such as this should also trigger the automatic
global value printing logic:
probe foo { var ++ }
global var
but it doesn't, because the tree analysis visitor used for this purpose
treats the "++" operation as both read and write of the variable. This
may be true for locking or some other purposes, but given that the value
is thrown away, it really is just a "write". Therefore it should trigger
automagic printing.

global var
