George Steed ba0bba5b2b [AArch64] Use getauxval(AT_HWCAP{,2}) for feature detection 
This has the advantage of also working under emulation where
faking /proc/cpuinfo is not supported.

For the Chromium sandbox, getauxval is supported since API version 18.
The minimum supported API version at time of writing is 21 so we should
be able to use getauxval unconditionally. On the off-chance the call
fails it will return 0 and we will correctly fall-back to using only
Neon.
