Hello all;

This change backs out use of the optimized for debugging "-Og" in favour of the traditional "-O0". Initial evaluation seemed to indicate that "-Og" provided all the necessary debugging information but this has turned out to be incorrect. It seems that information is missing with the "-Og" optimization option combined with the default "-g" symbols option. More investigation is needed but that will be done in a future changeset.

(diffs in the generated configure script are not part of this review)

The changes will be pushed through the hotspot-compiler repo.
