RFR: JDK-7107013: sun.jvm.hotspot.runtime.Bytes.swapLong conversion to long mishandled

[Sharath Ballal]

Thanks Dmitry.  I have made the changes in line 54.

I didn't change the recursive calls to swap functions because that looks more readable.

Sharath,

Please, add (int) to ll. 54 for better readability.

PS:

Despite the fact that C2 does a great job eliminating useless code (multiple calls to if (!swap) in this case) it would be nice to use simple, well known arithmetic directly instead of subsequent calls to other swap functions.
