v3_core: Remove unused support for generating compilation errors
The state record #core{} has a "es" field that can be used for causing a compilation error. Since incorrect programs have been rejected much earlier by erl_lint, no errors were actually stored in the "es" fields. Therefore, get rid of the "es" field and the support for generating a compilation error in the v3_core module.
