// Execute one round of BLAKE2s by updating the state matrix v[0..15]. v[0..9]
// are in r0..r9. The stack pointer points to 8 bytes of scratch space for
// spilling v[8..9], then to v[9..15], then to the message block. r10-r12 and
// r14 are free to use. The macro arguments s0-s15 give the order in which the
// message words are used in this round.
//
// All rotates are performed using the implicit rotate operand accepted by the
// 'add' and 'eor' instructions. This is faster than using explicit rotate
// instructions. To make this work, we allow the values in the second and last
// rows of the BLAKE2s state matrix (rows 'b' and 'd') to temporarily have the
// wrong rotation amount. The rotation amount is then fixed up just in time
// when the values are used. 'brot' is the number of bits the values in row 'b'
// need to be rotated right to arrive at the correct values, and 'drot'
// similarly for row 'd'. (brot, drot) start out as (0, 0) but we make it such
// that they end up as (7, 8) after every round.
