Remove dead code

Earlopain · Earlopain · commit 42b4e4a17fdd · 2025-11-18T09:56:12.000+01:00
See https://bugs.ruby-lang.org/issues/21669#note-4 > At line 1067, void_node = vn is executed (and vn is guaranteed to be non-NULL on the line above), so it's impossible for void_node to be NULL at line 1075. Thus, it is indeed dead code.
