Fixed VSTELM_D wrong idx compared with VPICKVE2GR_D hi64 and lo64:

   0xfff6aed5c8:    addi.d    $r6,$r12,16(0x10)
   0xfff6aed5cc:    vpickve2gr.d    $r7,$vr2,0x1 ; hi64
(gdb) i r $vr2
vr2            {v16i8 = {0x6e, 0x50, 0xc8, 0xe7, 0x88, 0xe4, 0x68, 0x40, 0xfc, 0x40, 0x9d, 0xd3, 0x5e, 0x26, 0xe9, 0x3f}, v8i16 = {0x506e, 0xe7c8, 0xe488, 0x4068, 0x40fc, 0xd39d, 0x265e, 0x3fe9}, v4i32 = {0xe7c8506e, 0x4068e488, 0xd39d40fc, 0x3fe9265e}, v2i64 = {0x4068e488e7c8506e, 0x3fe9265ed39d40fc}, v4f32 = {0x0, 0x3, 0x7e080000, 0x1}, v2f64 = {0xc7, 0x0}}
