(*) For comparisons, k specifies what condition the test should accept
(true or false).
(*) For OP_LTI/OP_LEI, C indicates that the transformations
(A<B) => (!(B<=A)) or (A<=B) => (!(B<A)) were used to put the constant
operator on the right side. (Non-total orders with NaN or metamethods
use this indication to correct their behavior.)
(*) All 'skips' (pc++) assume that next instruction is a jump.
(*) In instructions OP_RETURN/OP_TAILCALL, 'k' specifies that the
