RFR [jdk11]: 8139876 : Exclude hanging nsk/stress/stack from execution with deoptimization enabled

[Baesken, Matthias]

Hello, please review the jdk11  backport of    8139876<https://bugs.openjdk.java.net/browse/JDK-8139876> : Exclude hanging nsk/stress/stack from execution with deoptimization enabled   .
The changes adds  a

"@requires vm.opt.DeoptimizeALot == null | vm.opt.DeoptimizeALot == false"

To a number of tests. This fits into jdk11 mostly as well, however a "clean" patch did not work because jdk11 has changes  below the added line .
