With bug 1543212 we'll have new Android ARM64 PGO builds, but to actually ship them we'll need to enable PGO on the Nightlies (like ARMv7 Nightlies bug 1535364).

Depends on: 1535364

Looks like PGO has improved AArch64 Android's Speedometer score by ~9% (~22 -> ~24)! ARMv7 Android has a higher score for now because ARMv7's JavaScript JIT is more mature.
