Truffle-DSL: some fixes and optimizations to the generated code. Fixed polymorphic specialization nodes could still reference children in some cases. Removed generation of getCost methods since they were very expensive to call. Removed generation of copyPolymorphic, setNext0. Made generated executeGeneric0 and executeAndSpecialize0 final.

# GraalVM Changelog

## `tip`
### Graal
* New methods for querying memory usage of individual objects and object graphs in Graal API (MetaAccessProvider#getMemorySize, MetaUtil#getMemorySizeRecursive).
* New (tested) invariant that equality comparisons for JavaType/JavaMethod/JavaField values use .equals() instead of '=='.
* Made graph caching compilation-local.

### Truffle
* New API TruffleRuntime#createCallNode to create call nodes and to give the runtime system control over its implementation.
* New API RootNode#getCachedCallNodes to get a weak set of CallNodes that have registered to call the RootNode.
* New API to split the AST of a call-site context sensitively. CallNode#split, CallNode#isSplittable, CallNode#getSplitCallTarget, CallNode#getCurrentCallTarget, RootNode#isSplittable, RootNode#split.
* New API to inline a call-site into the call-graph. CallNode#isInlinable, CallNode#inline, CallNode#isInlined.
* New API for the runtime environment to register CallTargets as caller to the RootNode. CallNode#registerCallTarget.
* Improved API for counting nodes in Truffle ASTS. NodeUtil#countNodes can be used with a NodeFilter filter Nodes.
* New API to declare the cost of a Node for use in runtime environment specific heuristics. See NodeCost, Node#getCost() and NodeInfo#cost().
* Removed old API for NodeInfo#Kind and NodeInfo#kind(). As a replacement the new Node cost API can be used.
* Changed Node#replace reason parameter type to CharSequence (to allow for lazy string building)
* Deprecated Node#adoptChild and Node#adoptChild, no longer needed in node constructor
* New Node#insert method for inserting new nodes into the tree (formerly adoptChild)
* New Node#adoptChildren() helper method that adopts all (direct and indirect) children of a node
* New API Node#atomic for atomic tree operations
* Made Node#replace thread-safe
