[GlobalISel] support widen unmerge if WideTy > SrcTy
Summary:
Widening G_UNMERGE_VALUES to a type which is larger than the
original source type is the same as widening it to the same
type as the source type: in both cases, G_UNMERGE_VALUES has
to be replaced with bit arithmetic which. Although the arithmetic
itself is independent of whether the source type is smaller
or equal to the widen type, widening the source type to the
widen type should result in less artifacts being emitted,
since this is the type that the user explicitly requested.
