* AES S-box is:
* S(x) = A(I(x)) ^ 0x63
* where I() is inversion in GF(256), and A() is a linear
* transform (0 is formally defined to be its own inverse).
* Since inversion is an involution, the inverse S-box can be
* computed from the S-box as:
* iS(x) = B(S(B(x ^ 0x63)) ^ 0x63)
* where B() is the inverse of A(). Indeed, for any y in GF(256):
* iS(S(y)) = B(A(I(B(A(I(y)) ^ 0x63 ^ 0x63))) ^ 0x63 ^ 0x63) = y
*
* Note: we reuse the implementation of the forward S-box,
* instead of duplicating it here, so that total code size is
* lower. By merging the B() transforms into the S-box circuit
* we could make faster CBC decryption, but CBC decryption is
* already quite faster than CBC encryption because we can
* process two blocks in parallel.
