[aarch64-port-dev ] [10] RFR: 8187472 - AARCH64: array_equals intrinsic doesn't use prefetch for large arrays

[Dmitrij Pochepko]

Hi,

please take a look at merged simd/non-simd version.

I've set ergonomics to use non-simd version on ThunderX, because simd is 
about 15% slower there.

R-Pi shows about the same results for both versions.

Thanks,

Dmitrij
