Attached patch implements a bitops test for 64 bit ints. Platforms where
$PConfig{intvalsize} != 8 are skipped. It covers the issues I had trouble with
concerning the shl, band, and bor ops.
I haven't managed to beat ICU into submission on AIX yet, so I can't test it out
anywhere but AMD64. It's worth monitoring other 64-bit arches to see if the test
passes.
