arm64: Implement VarHandle intrinsics for byte array views.
Using benchmarks provided by
https://android-review.googlesource.com/1420959
on blueline little cores with fixed frequency 1420800:
before after
GetByteArrayViewInt 27.093 0.024
SetByteArrayViewInt 28.067 0.024
GetByteArrayViewBigEndianInt 27.142 0.026
SetByteArrayViewBigEndianInt 28.040 0.025
Test: testrunner.py --target --64 --optimizing
