* @file test_CodeTester.cpp
* Tests for the CodeTester, a tool for testing the emitter by emitting code and running it
* from within the test application.
*
* These tests should just make sure the basic functionality of CodeTester works, and that it
* can generate prologues/epilogues, and execute them without crashing.
