Review request for JDK-8057148

[Hannes Wallnoefer]

+1, nice work!

There's an if-statement in line 759 of AssignSymbols.java that is 
missing braces and indentation.

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?
