Add miscellaneous tests for class redefinition.
There were a bunch of edge cases related to class redefinition and
obsolete methods that were never explicitly tested. This adds tests
for some of them.
Specifically we add the following tests:
1) Testing throwing exceptions that move through obsolete methods.
2) Testing Method.invoke of redefined methods.
Test: mma -j40 test-art-host
