Improve comments for execExpr.c's handling of FieldStore subexpressions. Given this code's general eagerness to use subexpressions' output variables as temporary workspace, it's not exactly clear that it is safe for FieldStore to tell a newval subexpression that it can write into the same variable that is being supplied as a potential input. Document the chain of assumptions needed for that to be safe.
