[SelectionDAG] Don't scalarize vector fpround sources that don't need it.
Similar to the workaround code in ScalarizeVecRes_UnaryOp, ScalarizeVecRes_SETCC
, ScalarizeVecRes_VSELECT, etc.
If we have a case like this:
```
define <1 x half> @func(<1 x float> %x) {
%tmp = fptrunc <1 x float> %x to <1 x half>
ret <1 x half> %tmp
}
```
On AArch64, the <1 x float> is legal. So, this will crash if we call
GetScalarizedVector on it.
