rs6000: Update bswap64-4 test to reflect actual results
Hi,
Update existing testcase powerpc/bswap64-4.c to
reflect that we generate ldbrx and stdbrx instructions
for newer cpu targets. This is in contrast to the
pair of lwbrx and stwbrx instructions that are
generated with older cpu targets.
OK for mainline?
Thanks,
-Will
