v3_core: Don't depend on sys_core_fold for cleaning up
v3_core would generate unsafe code for the following example: f() -> {ok={error,E}} = foo(), E. Internally, the code would look similar to: f() -> Var = foo(), error({badmatch,Var}), E. That is, there would remain a reference to an unbound variable. Normally, sys_core_fold would remove the reference to 'E', but if if optimization was disabled the compiler would crash.
