  [AArch64] NFCI: Simplify LowerVectorFP_TO_INT_SAT (part 1) (#207198)

The lowering code tries to implement splitting by keeping two source
values SrcVal and SrcVal2 for the Lo/Hi part respectively.

This is a bit awkward, because SrcVal2 may not be set. It makes more
sense to generating new DAG nodes that will be lowered separately by the
lowering mechanism, which revisits the newly added (split sourceval)
nodes for lowering.
