The implementation of the espresso context vm access is partial and is done as a refactoring of Espresso's existing "internal" JVMCI implementation. * On the JVMCI side, the main espresso JVMCI implementation classes are turned into abstract classes that are extended by 2 sublasses: one for internal JVMCI which works as before via substitutions of native methods; and one for the new external JVMCI which is implemented via polyglot interop. * In espresso, some common code is moved from the existing substitution classes to some *Util classes. External JVMCI works over interop so some exisiting classes now implement interop and a number of new interop wrappers to util objects are introduced. --- compiler/mx.compiler/suite.py | 126 +++
