    Special graph node to represent accumulation of the operation costs.

    Special graph node to represent accumulation of the operation costs. In general, due to node sharing it is incorrect to just sum up all the args costs and add resCost to that value. Example:
    val x = .. val y = op1(x) val z = op2(x) val res = op3(y, z) The naive summation will lead to the cost of x is accumulated both into cost of y and into cost of z, so in the cost of res it is accumulated twice. To avoid this problem OpCost nodes require special handling in during evaluation.

    Implicit injection of new definition (graph node) into universum of nodes with collapsing semantics.

    Implicit injection of new definition (graph node) into universum of nodes with collapsing semantics. If there exists node n in this IR such that obj equals n, then the value of n.self is returned, i.e. the new node obj is collapsed with already existing one. This has an effect of Common Subexpression Elimination (CSE) when an expression tree is transformed to the graph and identical subtrees are collapsed. After a reference to the node is obtained, global rewriting rules are examined and the reference may be replaced with a new one.
