[Anton Kozlov]

> Hi, please review a merge of openjdk/jdk:master into jdk-macos branch. Once reviewed, I'm going to propose the result of this merge as JEP-391 implementation to jdk:master. 
> 
> There is non-trivial changes in gtest to avoid fighting with W^X asserts. Now gtests are started in Write mode, as if they are running in the VM context.
