Test aot agent retransform

[adinn]

This test checks whether compiled training data might be included in an AOT cache that was derived from inlined code that got transformed.

Specifically, the test executes multiple calls to a method ShouldNotBeTransformed::doWork() which calls out to ShouldBeTransformed::doWork(int) to do some actual computation.

ShouldBeTransformed is then transformed so that method ShouldBeTransformed::doWork(int) simply returns its argument.

The calls to ShouldNotBeTransformed::doWork() are rerun, this time exercising the simplified version of ShouldBeTransformed::doWork(int).

The tests includes checks to verify that ShouldNotBeTransformed::doWork() is compiled during the training run and that ShouldBeTransformed::doWork(int) inlined.

In the assembly run the test enables printing of training data. The test fails if it detects the presence of compile method training data for ShouldNotBeTransformed::doWork().
