RFR: 8250670: TestJFRIntrinsic.java should be run with and without JFR to check the intrinsic properly

[Mario Torre]

Hi all,

We noticed an interesting thing with TestJFRIntrinsic.java, if I
understood the test correctly, it wants to check the behavior of the
getEventWriter intrinsic, however it doesn't really do this, since JFR
is always disabled when the test starts, the instance is always null.

I changed the test slightly, first of all it's run twice now (actually
4 times, since it was already run twice before with different values
of the TieredStopAtLevel option), one with and one without JFR, I also
check that for the given combinations we get something resembling
meaningful results.

Here's the webrev:

Any comments?

Cheers,
Mario
