Calculate ROM for MCLT fold indices:
A0..A1 - variant, folding to the same 8x8 sample
A2..A4 - sample column in folded 8x8 tile
A5..A7 - sample row in folded 8x8 tile
D0..D4 - pixel column in 16x16 tile
D5..D7 - pixel row in 16x16 tile
D8 - negate for mode 0 (CC)
D9 - negate for mode 1 (SC)
D10 - negate for mode 2 (CS)
D11 - negate for mode 3 (SS)
