  -----------
  [SLP] Update vector value for incoming phi node, beeing vectorized already

If the phi node contains multiple same incoming blocks/values, need to
update the corresponding vectorized value, if it is not going to be
vectorized, if the incoming value was vectorized already.

Fixes #131355
