  [SLP]Fix a crash for buildvector nodes with parent phi nodes with same incoming blocks

If trying to find matching buildvector node for another nodes, and both
nodes are used by vectorized phi nodes and are coming from the same
parent block, this nodes should be considered matched to avoid a crash.
