Fixed a bug int the new version of Long.reverse introduce in change Id6bd7c81.
The corresponding code in Hacker's Delight is written in C, which supports
unsigned numbers. In Java, it's essential to use explicit unsigned shifts,
but I neglected to do so.  This bug was caught by jtreg test
java.lang.Long.BitTwiddle (which I wrote in 2003).  This preexisting
test serves as the regression test for this change.
