1.0.8.18: Fix gc-safety bug in x86oid function calls

         * Off by one error in conservative stack scavenging, the top of the
           stack wasn't pinned.
         * In the new calling convention there is a small window during which
           the return address only exists on the top of the stack. If a gc
           was triggered during that window, the code object could move, and
           the return address would point to freed memory.
