For VLD3 (single 3-element structure to one lane), there is no alignment specification and the alignment bits in the instruction must be zero. This is bit [4] for the size=0 and size=1 cases, and bits [5:4] for the size=2 case. We do this check correctly in VLDST_single(), but we write it a bit oddly: in the 'case 3' code we check for bit 0 of a->align (bit [4] of the insn), and then we fall through to the 'case 2' code which checks bit 1 of a->align (bit [5] of the insn) in the size 2 case. Replace this with just checking "is a->align non-zero" for VLD3, which lets us drop the fall-through and put the cases in this switch in numerical order.
