This CR is related to a closed JEP. Its main objective is to support the template interpreter in highly secure contexts where dynamically generated code is not allowed.

Most of the implementation is in the closed part of the hotspot forest.

The open part mostly consists of simple calls to a new CodeCacheExtensions class which allows closed code to load a pregenerated template interpreter (+all stubs required for the interpreter to work well). The same API is also used to pregenerate this code.

These are HotSpot internals only, not accessible to the end-user Java application.
