Add a new method to the AST nodes, 'bool_value'.
It is used to deduce the value of a node when used in a boolean context, which is useful
for both inference, as well as for data flow analysis, where we are interested
in what branches will be followed when the program will be executed.
`bool_value` returns True, False or YES, if the node's boolean value can't
be deduced. The method is used when inferring the unary operand `not`.
Thus, `not something` will result in calling `something.bool_value` and
negating the result, if it is a boolean.
