  1. feat(core) EspressoVM compatibility 

    `reserved0` is used by EspressoVM, thus it cannot serve as a "reference NULL" as on HotSpot:
https://github.com/oracle/graal/blob/3149f62458029ffe92b8dcefe0b3e59612684cfa/espresso/src/com.oracle.truffle.espresso.mokapot/include/mokapot.h#L67-L73

The relevant config is `MOKA_LATTE`. `reserved3` is `NULL` though.
