target/arm/translate-a64: Don't underdecode SIMD ld/st single
In the AdvSIMD load/store single structure encodings, the
non-post-indexed case should have zeroes in [20:16] (which is the
Rm field for the post-indexed case). Bit 31 must also be zero
(a check we got right in ldst_multiple but not here). Correctly
UNDEF these unallocated encodings.
