RFR: 8314275: Incorrect stepping in switch [v2]

[Aggelos Biboudis]

> In code like the one below, the observable effect was that if the user debugs the following method, `multiply` called with `1`, the debugger steps from line 4 to line 6 (instead of 7) giving the impression that line 6 is going to be executed. The reason is that the `LineNumberTable` did not include an entry at the end of the `switch` mapping the statement that follows, to bytecode.

> 9 }
