[7u-dev] Request for Review + Request for Approval to Backport: 8064846: Lazy-init thread safety problems in core reflection

[Ivan Gerasimov]

Hello!

This is a request to approve the partial backport of the fix JDK-8064846.
The backport is very similar to the one for jdk8u.
I only had to modify GenericDeclRepository.java a bit due to omitted 
generics.

Tested with JPRT with jdk_lang subset of tests.
No failures introduced.
