fix mark bit operation.
To optimize the sweep phase, there is bit operation to set mark
bits for out-of-range bits in the last bit_t.
However, if there is no out-of-ragnge bits, it set all last bit_t
as mark bits and it braek the assumption (unmarked objects will
be swept).
GC_DEBUG=1 makes sizeof(RVALUE)=64 on my machine and this condition
happens.
It took me one Saturday to debug this.
