ART: Remove unneeded SideEffects for fatal instructions.
Remove "CanTriggerGC" side effect for NullCheck, BoundsCheck and
DivZeroCheck - instructions which have fatal slow paths. Even though
GC might happen after going through those instructions' slow path
execution doesn't return to the next instruction after the
exceptional one so side effects can be relaxed.
Performance improvement (angler, arm64, little core):
- Geomean: 2.8%
- Particular benchmarks
- algorithm/Sort.SystemSort: 13.0%
- stanford/IntMM: 12.7%
- stanford/Puzzle: 9.5%
- benchmarksgame/revcomp: 8.9%
- reversigame/Reversi: 3.5%
Test: 510-checker-try-catch.
Test: 706-checker-scheduler.
Test: 527-checker-array-access-split.
Test: test-art-host, test-art-target.
