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.
