8008199: Lazy compilation and trampoline implementation
Summary: The code pipeline now supports lazy compilation, which can be used to only compile certain FunctionNodes and leave others be, saving startup time. When these uncompiled nodes are hit, a trampoline will force them to be recompiled. This can also be used to specialize compilation fixing parameter types and return types to a callsite specific compilation. This will give performance.
