    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.

    lambdaVar

    the variable of the lambda in which scope this node is created. This makes this node belong to the lambda body, even if it doesn't otherwise depend on lambda argument.

    costedValueId

    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.

    This method is called for each MethodCall node which is about to be added to the graph.

    This method is called for each MethodCall node which is about to be added to the graph. This means mc has been examined by all the rewrite rules, but has not need rewritten. Now, if this method returns null, then mc will be added to the graph. However, in this method, mc can be examined by a second set of RW rules (kind of lower priority rules). These rules kind of context dependent, because at this point we know that the first RW set didn't triggered any rewrite.

This method returns dynamically constructed instance, which conforms to T. Whenever a method of T is called on that instance, the call is intercepted and DelegatedInterceptionHandler.invoke method is called, then a new MethodCall can be constructed (which is befavior by default).
