8009868: For loop with "true" as condition results in AssertionError in codegen Reviewed-by: jlaskey, hannesw, lagergren

8009718: Lazy execution architecture continued - ScriptFunctionData is either final or recompilable. Moved ScriptFunctionData creation logic away from runtime to compile time. Prepared for method generation/specialization. Got rid of ScriptFunctionImplTrampoline whose semantics could be done as part of the relinking anyway. Merge with the lookup package change.
