children method in LLINT AST Not class should return [@child]

[lds]

While experimenting with the new llint in JSCore,  I noticed that the
Not class (located in offlineasm/ast.rb) may have an incorrect method:

class Not < Node
    attr_reader :child

    def initialize(codeOrigin, child)
        super(codeOrigin)
        @child = child
    end

    def children
        [@left, @right]
    end

    def mapChildren
        Not.new(codeOrigin, (yield @child))
    end

    def dump
        "(not #{child.dump})"
    end
end



Shouldn't children of this 'Not' class be

    def children
        [@child]
    end

instead, since it's  a unary operator?

I think this is also a problem. So this patch should fix it.

This patch can not cause this fail, because at this time the 'Not' node is not used at all.
