	We assume that instructions are unsigned numbers.
	All instructions have an opcode in the first 6 bits.
	Instructions can have the following fields:
				'A' : 8 bits
				'B' : 9 bits
				'C' : 9 bits
				'Bx' : 18 bits ('B' and 'C' together)
				'sBx' : signed Bx

	A signed argument is represented in excess K; that is, the number
	value is the unsigned value minus K. K is exactly the maximum value
	for that argument (so that -max is represented by 0, and +max is
	represented by 2*max), which is half the maximum for the corresponding
	unsigned argument.

	Notes:
	(*) In OP_CALL, if (B == 0) then B = top. C is the number of returns - 1,
			and can be 0: OP_CALL then sets 'top' to last_result+1, so
			next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use 'top'.
	(*) In OP_VARARG, if (B == 0) then use actual number of varargs and
			set top (like in OP_CALL with C == 0).
	(*) In OP_RETURN, if (B == 0) then return up to 'top'
	(*) In OP_SETLIST, if (B == 0) then B = 'top';
			if (C == 0) then next 'instruction' is real C
	(*) For comparisons, A specifies what condition the test should accept
			(true or false).
	(*) All 'skips' (pc++) assume that next instruction is a jump
