There was a typo in the pipeline description where DUP was assigned to

performance (there's a very small bump of 1.7% in x264 but that's
about it) in my tests but is the more precise description of operations
for falkor.
Bootstrapped and tested with --with-cpu=falkor to confirm that there
are no regressions.
OK.
Thanks, may I backport this to gcc 8.x as well given that it has zero
impact on anything except falkor? We are targeting gcc 8.x as the
toolchain for falkor and so would like to at least get all falkor
specific optimizations and fixes back into the gcc 8.x branch.
