History
David Benjamin a2d4c0c426 Work around Android devices without AT_HWCAP2. 
Some ARMv8 Android devices don't have AT_HWCAP2. This means, when running in
32-bit mode (ARM capability APIs on Linux are different between AArch32 and
AArch64), we can't discover the various nice instructions.

On a Nexus 6P, this gives a, uh, minor performance win when running in 32-bit
mode.
