Do type checks in ArraySet without read barriers.
This approach is valid in the case of Baker and non-Baker
read barriers.
Benchmarks (ARM64) score variations on Nexus 5X with CPU
cores clamped at 960000 Hz (aosp_bullhead-userdebug build,
medians of 10 runs for each suite):
- Ritzperf - average (lower is better): -0.44% (virtually unchanged)
- CaffeineMark - average (higher is better): -0.20% (virtually unchanged)
- DeltaBlue (lower is better): -4.08% (slightly better)
- Richards - average (lower is better): -0.57% (virtually unchanged)
- SciMark2 - average (higher is better): -0.52% (virtually unchanged)
Details about Ritzperf benchmarks with meaningful variations
(lower is better):
- GenericCalcActions.MemAllocTest: +3.02% (slightly worse)
Details about Richards benchmarks with meaningful variations
(lower is better):
- gibbons -5.01% (better)

(aosp_bullhead-userdebug build):
- total ARM64 framework Oat files size change:
