Richard Sandiford acb31a245c Handle masked rotate amounts ...

At the moment we expect rotates to have the form:

   (or (shl X, Y), (shr X, Z))

where Y == bitsize(X) - Z or Z == bitsize(X) - Y.  This form means that
the (or ...) is undefined for Y == 0 or Z == 0.  This undefinedness can
be avoided by using Y == (C * bitsize(X) - Z) & (bitsize(X) - 1) or
Z == (C * bitsize(X) - Y) & (bitsize(X) - 1) for any integer C
(including 0, the most natural choice).
