Add support for registering classpath classes status.

By doing class unloading after each dex file compilation, we are loosing
away verification done on classpath classes.

This change introduces a new table for keeping around class status of
classpath classes.

Multidex quickening compilation improved by ~5% by not re-verifying classpath
classes.
