fortress typecheck success causes subsequent fortress compile to silently generate no code

[jmaessen]

Running fortress typecheck puts the cache into a state in which it believes that code has been generated. Thus the following:

ant -e cleanCache
fortress typecheck ProjectFortress/compiler_tests/Compiled1.fss
fortress link ProjectFortress/compiler_tests/Compiled1.fss
fortress run Compiled1

Fails as follows:

Exception in thread "main" java.lang.NoClassDefFoundError: Compiled1
Caused by: java.lang.ClassNotFoundException: Compiled1
	at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:319)
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:254)
	at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:402)

By contrast, eliminating the typecheck step succeeds:

ant -e cleanCache
fortress link ProjectFortress/compiler_tests/Compiled1.fss
fortress run Compiled1
