Provides part of fixes for: https://bugs.openjdk.org/browse/JDK-8363440
Fixes: https://bugs.openjdk.org/browse/JDK-8369559

Right now, MethodTrainingData and CompileTrainingData do not show to what Method they belong to:

$ cat aot.map | grep MethodTrainingData
0x00000008019d54c0: @@ MethodTrainingData 96
0x00000008019dcec8: @@ MethodTrainingData 96
[...]

$ cat aot.map | grep CompileTrainingData
[...]
0x000000080079c8a0: @@ CompileTrainingData 80
0x00000008007a7660: @@ CompileTrainingData 80

Add the method name to those lines in the AOT map to add more context. Also, for CompileTrainingData, add the level of compilation.

The output should look like the following:

$ cat aot.map | grep CompileTrainingData
0x000000080079c8a0: @@ CompileTrainingData 80 3 int java.lang.Byte.hashCode()
0x00000008007a7660: @@ CompileTrainingData 80 3 java.lang.Object java.lang.ref.Reference.get()

Note the number before the method signature on CompileTrainingData that represents the level, important because there are two CompileTrainingData for the same method with different compilation levels.

Some elements have a nullpointer instead of a valid Method, and those will be represented without method signature (as they appear currently, with no changes).
