[Bug 727064]

FYI, this bug has bitten me in a different way: memcpy() copying
backwards defeats the MADV_SEQUENTIAL flag to madvise(). A trivial file
copier implementation (mmap source, mmap destination, set
MADV_SEQUENTIAL, memcpy from source to destination) would perform much
worse on machines that support SSSE3 than on machines that don't because
of this bug.

(Before anyone tells me that I should copy files using read() and
write(), my actual usage pattern was more complex, but the details are
irrelevant.)
