RFC: Pick up 11.0.5+1 to sh/jdk11

[Aleksey Shipilev]

Upstream had published 11.0.5+1 to jdk-updates/jdk11u. Let's pick that up to sh/jdk11!

There are many incoming changes, so webrev is not practical:
 49022 lines changed: 14616 ins; 6021 del; 28385 mod; 652850 unchg

List of changes:
 https://cr.openjdk.java.net/~shade/shenandoah/merges/jdk11-11.0.5%2b1/changesets.txt

I had to additionally pick up the leftover change from here:
  https://bugs.openjdk.java.net/browse/JDK-8223244
