Peter Maydell fc2a9b3784 target-arm: Handle UNDEF cases for Neon 2 register misc forms
Add missing UNDEF checks for Neon "two register miscellaneous" forms:
 * all instructions except VMOVN,VQMOVN must UNDEF
   if Q==1 && (Vd<0> == 1 || Vm<0> == 1)
 * VMOVN,VQMOVN,VCVT.F16.F32 UNDEF if Q == 1 || Vm<0> == 1
 * VSHLL,VCVT.F32.F16 UNDEF if Q == 1 || Vd<0> == 1
(The only other UNDEF case is VZIP,VUZP if Q == 0 && size == 10,
which we already handle.)
