Fix typo error in bit-vector tracking mechanism, causing bogus "seen before"s.

On 64 bit platforms which allocate on 8 byte alignment (rather than 16), a low
pointer bit could get lost, resulting in new pointers being considered already
"seen". Joy, hilarity, failing tests and different results running under gdb.
"Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. The help was
appreciated.
