Modified revert of "Add couple DexCache read-barriers."
Remove the DexCache read-barriers again (the revert) since
there is measurable performance difference in app startup (~1%).
It turns out they are on very hot path in the interpreter.
The lazy array initialization made the DexCache fields mutable.
However, instead of the read-barriers, we can just ensure we get
the right to-space object on the array-initialization slow path.
Test: test.py -b -r --host
