Subject: Improve bridge method test, bootstrapping ASM usage

Instead of using a pre-generated JAR, the source code generating the
class with reordered methods (bridge method first) is now compiled
directly before usage. This is possible, because in the previous commit
ASM was put on the Ajc classpath for tests.

Relates to #256.
