Avoid using dex cache array pointers in libart.
In preparation for making dex cache arrays native, avoid
using them in Java code.
This causes a performance regression for our reflection
benchmarks. Class_getDeclaredMethod and Class_getMethod
take an up to 30% hit, measured using the Quick compiler.
We accept this hit at this stage and we will tune the
performance after we're done with the larger effort.
