[PATCH] [AArch64] Override useAA and remove unneeded edges in the scheduling graph. (Phabricator)

[Jiangning Liu]

Hi Sanjin,

spec.cpu2000.ref.181_mcf -1.86%
spec.cpu2000.ref.183_equake -3.11%
spec.cpu2000.ref.186_crafty 1.53%
spec.cpu2000.ref.254_gap 1.40%

I can confirm that we only see some fluctuations on coretex-A57 as above,
so there isn't degradation observed for spec2000 at least.

Thanks,
-Jiangning
