Please review JDK-8057148 at <> for <>

It's the now (hopefully) final version of the code to skip nested functions in the parser when doing on-demand compilation. Notable changes to the surroundings include:

- FunctionNode no longer has an id field, but rather uses its Node.position() as its ID (also unique within a source file - :program always has 0, and functions typically have the position of their closing parameter list parenthesis for some reason, so even if the program starts with a function declaration, the function won't have 0). This had to be done otherwise an ID assignment algorithm on recompilations would've renumbered functions now that we're skipping nesteds. I tried exporting the IDs from RecompilableScriptFunctionData.nestedFunctions.keySet() but it turns out those were missing nested functions that are visible to the parser, but removed later in the pipeline as they're function expressions declared in dead code… I know, right?

- RecompilableScriptFunctionData now has a copy of FunctionNode.flags, instead of decomposing it into various booleans. This is needed to reconstruct correct flags on reparse.
