7ebbbd88 - [DAG] Always use stack to promote bitcast when the source is vector (#151065)

[DAG] Always use stack to promote bitcast when the source is vector (#151065) The optimization introduced by #125637 tried to avoid using stacks to promote bitcast with vector result type. However, it wouldn't be correct if the input type is vector. This patch limits that optimizations to only scalar to vector bitcasts.
