Hi all,

can I have reviews for this change that factors out before/after heap related printing into a single scoped object to be used for both young and full gc code?

There is some minor change in order of unrelated options (COMMIT/UNCOMMIT region state changes vs. other heap printing), during full gc but since this is very low level debugging I do not see a problem to do that.

Based on #4539 .
