shift: simplify ASR(LSR(x,N),N')
Since an LSR with an in-range shift count will insert a zero in
the MSB, a subsequent ASR will be equivalent to an LSR of the same
count or equivalently, the combinaison the these two shifts is
equivalent to a single LSR with a shift count equal to the sum
of the two initial counts.
