[11u] RFR (S) 8214118: HeapRegions marked as archive even if CDS mapping fails

[Aleksey Shipilev]

Please review the backport to 11u.

Original bug:
  https://bugs.openjdk.java.net/browse/JDK-8214118

Original fix:
  http://hg.openjdk.java.net/jdk/jdk/rev/c9325aa887da

The patch does not apply cleanly to 11u, because there are minute differences in the code. Notably,
there is no closed_archive_heap_ranges, and as I see from the code, string_ranges is the old name
for it. It was renamed in JDK-8212995.

I also see there is Oracle-closed backport to 11u-oracle, can we compare the patches with Oracle
folks, maybe?

Testing: Linux x86_64 tier1

Thanks,
