Make B::OP::slabbed, folded, etc. actually work

B::OP::slabbed       = 47
B::OP::savefree      = 48
B::OP::static        = 49
B::OP::folded        = 50

Added by 3164fde474, these have never worked, because the alias index
check in B::OP::next was never updated.

Instead of hard-coding the number, use C_ARRAY_LENGTH(...).
