This ASM has a different visitMethodInsn() instruction so
there are big changes throughout the code. The tests are running
fine but as new testcases are added related to Java8 we may need
further fixes to take account of the extra isInterface parameter
on visitMethodInsn()
- Split the AspectJ testcode out of the general testdata project.
- Adjusted tests to handle that JDT produces different code to AspectJ.
- Modified some tests to work better with javac compiled testdata (which
is what happens when building on the command line or build machine)
