RFR: 8248650: [BACKOUT] Backout JDK-8244603 because it generates too much noise in CI

[Thomas Schatzl]

Hi all,

  can I have quick reviews for this backout of JDK-8244603?

Since the checking of these changes that make young gen sizing quite different than before, there are a lot of crashes in tier7/tier8 testing. Dan Daugherty traced this back to the push of JDK-8244603.

At this time I do not think the change is directly the cause for this issue but rather exposing a latent bug; however to reduce the noise I would like to backout the change, and later reapply after fixing this issue.

The backout applied without issues if the build fix that had to be applied to it (JDK-8248329) is considered, i.e. this change is actually backing out 8248329 and 8244603.
