I get reproducible regressions on AArch64 as well with the latest patch
(changes >0.5%):

400.perlbench   -1.26%
403.gcc         -3.16%
445.gobmk       -2.70%
458.sjeng       1.65%
464.h264ref     -0.78%
453.povray      -2.65%

It seems this is worse than the earlier versions of the patch which all used
NOT_TAKEN.
