  [PowerPC] fix legalization crash (#105563)

If v2i64 scalar_to_vector is made custom, llc can crash in certain
legalization cases where v2i64 vectors are injected, even if they
weren't otherwise present. The code generated would be fine, but that
operation is not handled in ReplaceNodeResults. Add handling.
