ARM64: Support interm. address for object arrays.
Support IntermediateAddress on arm64 for object
array reads in Baker read barrier configuration.
The patch brings minor boot.oat size reduction and
performance improvement on Puzzle benchmark.
Test: test-art-target, test-art-host, gc_stress.
Test: 527-checker-array-access-split.
Bug: 26601270
Bug: 32578862
Change-Id: I781a911905038b36428964a990771fdf74e99bbd
