Add missing class initialization during compilation and tests

Adds missing class initialization during compilation and tests, especially
java.lang.Class. Otherwise, we'd be able to execute code while the referring
class is not initialized or initializing.

Also adds mirror::Class::AssertInitializedOrInitializingInThread method to
check class initialization when entering the interpreter: the called method's
declaring class must either be initialized or be initializing by the current
thread (other threads must be waiting for the class initialization to complete
holding its lock). Note we only do this check in debug build.

Bump oat version to force compilation.
