arm64: Implement VarHandle GetAndSet intrinsics.
Add an extra test to 160-read-barrier-stress. The main path
is sufficiently exercised by 712-varhandle-invocations.
Using benchmarks provided by

Test: testrunner.py --target --64 --optimizing
Test: Repeat with ART_USE_READ_BARRIER=false ART_HEAP_POISONING=true.
Test: Repeat with ART_READ_BARRIER_TYPE=TABLELOOKUP.
(Ignore two pre-existing checker test failures.)
