From b93a531e315e97ef00367099e6b5f19651936e20 Mon Sep 17 00:00:00 2001

Subject: allow bug table entries to use relative pointers (and use it on
x86-64)
Impact: reduce bug table size
This allows reducing the bug table size by half. Perhaps there are
other 64-bit architectures that could also make use of this.
