inlining and runtime interface related changes:
added codeSize() and compilerStorage() to RiMethod
HotSpotMethodResolved uses reflective methods instead of vmIds and survives compilations
HotSpotResolvedType.isInitialized not represented as field (can change)
inlining stores graphs into method objects and reuses them
