Support for synchronized native methods.

This change adds support for synchronized native methods by using
calls to MonitorEnter and MonitorExit on the JNIEnv*. There is
some tidying of the assembler and a straw man JNIEnv implementation.
The JNIEnv implementation just warns when MonitorEnter/Exit are called
and doesn't adhere to the correct JNIEnv layout.
