Richard Henderson d3a77b42de target-arm: Eliminate unnecessary zero-extend in disas_bitfield 
For !SF, this initial ext32u can't be optimized away by the
current TCG code generator.  (It would require backward bit
liveness propagation.)

But since the range of bits for !SF are already constrained by
unallocated_encoding, we'll never reference the high bits anyway.
