added snippets for lowering array creation and initialization (in NewObjectSnippets) made it possible to use node intrinsics with arguments that may only be constant when a snippet template is created rename: NewTypeArrayNode -> NewPrimitiveArrayNode removed HotSpotVMConfig.getArrayOffset() - Kind.arrayBaseOffset() is used instead renamed field prototypeHeader to initialMarkWord in HotSpotResolvedJavaType rename: NewInstanceSnippets -> NewObjectSnippets renamed node intrinsics in DirectObjectStoreNode to include the type of the value being stored (to avoid accidental misuse) extended WordTypeRewriterPhase such that ObjectEqualsNodes are replaced with IntegerEqualsNodes when the values being compared are words (which allows '==' and '!=' to be used between Word values in Java source code)
