New bigger bytecode for small lambda in b79

[Eric Caspole]

Hi Lambda people,
I am not sure if this is lambda specific or not, but this is what we 
found. For a small test case like this:

	  java.util.stream.Streams.intRange(FROM, SIZ, 
STEP).parallel().forEach(p -> {ary[p]+= inc;});

The bytecode of the lambda is different this week. It all works but we 
were wondering why it is so much bigger. This new bytecode also happens 
in the lambda-8-b79-linux-x64-25_feb_2013.tar.gz snapshot.

Regards,
Eric


Old bytecode of lambda from last week:

   private void lambda$0(int, int);
     flags: ACC_PRIVATE, ACC_SYNTHETIC
     Code:
       stack=4, locals=3, args_size=3
          0: aload_0
          1: getfield      #3                  // Field ary:[I
          4: iload_2
          5: dup2
          6: iaload
          7: iload_1
          8: iadd
          9: iastore
         10: return
       LineNumberTable:
         line 57: 0


New bytecode generated since about Friday:

   private void lambda$0(int, int);
     flags: ACC_PRIVATE, ACC_SYNTHETIC

          4: astore_3
          5: aload_3
          6: iload_2
          7: aload_3
