Fix compiler class initialization to properly deal with super classes
Also moving active parts of compiler_test to be oat tests including
IntMath and Invoke. Added an interface invocation test case to Invoke
test. Changed Compiler to CHECK that it is not used once the
Runtime::IsStarted, forcing some jni_compiler_test to have two phases,
one for compiling before Runtime::Start and one for JNI operations
after the Runtime::IsStarted.
Finally, fixed Class::CanPutArrayElementFromCode by removing
CanPutArrayElement and calling IsAssignableFrom directly.
