Vitaly Chikunov 94f040aaec target/ppc: Fix rlwinm on ppc64 
rlwinm cannot just AND with Mask if shift value is zero on ppc64 when
Mask Begin is greater than Mask End and high bits are set to 1.

Note that PowerISA 3.0B says that for `rlwinm' ROTL32 is used, and
ROTL32 is defined (in 3.3.14) so that rotated value should have two
copies of lower word of the source value.

This seems to be another incarnation of the fix from 820724d170
("target-ppc: Fix rlwimi, rlwinm, rlwnm again"), except I leave
optimization when Mask value is less than 32 bits.
