Revert "Revert "Enable IntermediateAddress for primitive arrays with read barriers.""

This reverts commit 4a3aa578.

The failing assertion (see b/30762467):

08-09 11:32:46.767  1654  1656 F dex2oatd: art/compiler/optimizing/register_allocation_resolver.cc:325] Check failed: interval->GetDefinedBy()->IsActualObject() IntermediateAddress@InstanceFieldGet

that motivated the initial revert has been removed by a
previous CL (commit
70e97462,
https://android-review.googlesource.com/#/c/254920/).

Test: ART host and target (ARM, ARM64) tests with `ART_USE_READ_BARRIER=true`.
